BRIEF SUMMARY OF THE INVENTION
This invention relates to novel hydroxy substituted prostanoic acids and derivatives as well as to intermediates and methods for their preparation. These methods embrace novel and useful procedures for the preparation of prostaglandin E.sub.1, 11-deoxyprostaglandin E.sub.1, 13-dihydroxyprostaglandin, E.sub.1, and other known biologically important prostaglandin congeners. The novel compounds of this invention may be represented by the following general formula: ##STR1## wherein n is an integer having the value 1 or 2; R.sub.1 is hydrogen, lower alkoxy, triphenylmethyl, or triphenylmethyl in which one or two of the phenyl rings is substituted with an alkyl or an alkoxy group having up to 3 carbon atoms; R.sub.2 is a straight chain alkyl group having from 2 to 10 carbon atoms, a straight chain alkyl group having from 2 to 10 carbon atoms and substituted with one or two alkyl groups each having from one to three carbon atoms, a straight chain alkenyl group having from 3 to 10 carbon atoms, a straight chain alkenyl group having from 3 to 10 carbon atoms and substituted with one or two alkyl groups having between them from 2 to 5 carbon atoms, or a straight chain alkynyl group having from 3 to 10 carbon atoms; R.sub.3 is hydroxy or an alkoxy group having from 1 to 10 carbon atoms; Y is a divalent radical selected from the group consisting of those of the formulae: ##STR2## Z is a divalent radical selected from the group consisting of those of the formulae: ##STR3## wherein m is an integer from 3 to 8, inclusive, p is an integer from 2 to 6 inclusive, R.sub.4 is an alkyl group having up to 3 carbon atoms, and R.sub.5 is an alkyl group having up to 3 carbon atoms, a fluorine atom, or a phenyl group; R.sub.6 is hydrogen or an alkyl group having up to three carbon atoms; R.sub.7 is hydrogen or an alkyl group having up to 3 carbon atoms; and the moiety --C.sub.13 --C.sub.14 -- is ethylene, trans-vinylene, or cis-vinylene; with the first proviso that when n is 1, R.sub.1 is hydrogen, R.sub.7 is hydrogen, Z is --(CH.sub.2).sub.m -- and --C.sub.13 --C.sub.14 -- is ethylene or trans-vinylene then R.sub.2 does not include a straight chain alkyl group having from 2 to 10 carbon atoms; and with the second proviso that when Z is ##STR4## R.sub.1 is hydrogen, R.sub.2 is a straight chain alkyl group having from 2 to 10 carbon atoms and R.sub.7 is hydrogen then --C.sub.13 --C.sub.14 -- is ethylene or cis-vinylene; and with the third proviso that when R.sub.4 is alkyl then R.sub.1 is hydrogen; and with the fourth proviso that only one unsaturated bond can be directly adjacent to C.sub.13 ; and with the fifth proviso that when R.sub.7 is an alkyl group then the groups attached to the C.sub.8 position may have the 8a-alkyl(8-iso) configuration of the formula: ##STR5##
Embraced within the scope of the present invention are all the possible optical isomers of the above general formula. Also embraced within the scope of the present invention are the non-toxic, pharmaceutically acceptable salts of the novel compounds of the present invention when R.sub.3 is hydroxy. The cations comprised in these salts include, for example, the non-toxic metal cations such as the sodium ion, potassium ion, calcium ion, and magnesium ion as well as the organic amine cations such as the tri(lower alkyl)amine cations (e.g., triethylamine, triethanolamine) procaine, and the like.
The novel compounds of the present invention are usually obtainable as oils having characteristic absorption spectra. They are relatively insoluble in water but are relatively soluble in common organic solvents such as ethanol, ethyl acetate, dimethylformamide, and the like. The cationic salts of the compounds when R.sub.3 is hydroxy are, in general, white to yellow crystalline solids having characteristic melting points and absorption spectre. They are relatively soluble in water, methanol, and ethanol but are relatively insoluble in benzene, diethyl ether, and petroleum ether.
DETAILED DESCRIPTION OF THE INVENTION
The prostaglandins are a family of closely related compounds which have been obtained from various animal tissues, and which stimulate smooth muscle, lower arterial blood pressure, antagonize epinephrine-induced mobilization of free fatty acids, and have other pharmacological and autopharmacological effects in mammals. See Bergstrom et al., J. Biol. Chem. 238, 3555 (1963) and Horton, Experientia 21, 113 (1965) and references cited therein. All of the so called natural prostaglandins are derivatives of prostanoic acid: ##STR6## The hydrogen atoms attached to C-8 and C-12 are in trans-configuration. When the two side-chains (or the C-8 and C-12 hydrogens) are cis to each other, the compounds are referred to as 8-iso prostaglandins. The natural prostaglandins represent only one of the possible optical isomers. The compounds of this invention include all possible optical isomers.
The novel compounds of the present invention may be readily prepared from certain cycloalkenone intermediates which may be represented by the following general formula: ##STR7## wherein R'.sub.3 is an alkoxy group having from 1 to 12 carbon atoms; and n and Z are as hereinabove defined.
The cycloalkenone intermediates may be readily prepared from 2-carbethoxycyclopentanone or 2-carbethoxycyclohexanone in accordance with the reaction schemes set forth in Flowsheets A, B, C, I and J. ##STR8## wherein m and n are as hereinabove defined and X is iodo or bromo. In accordance with this reaction scheme, the cycloalk-2-en-1-ones (VIII) are developed by first converting 2-carbethoxycyclopentanone or 2-carbethoxycyclohexanone (I) to the sodium enolates thereof by means of sodium hydride in dimethoxyethane and then treating the sodium enolate with an ethyl .omega.-haloalkanoate (II). There is thus obtained the corresponding 2-carbethoxy-2-(.omega.-carbethoxyalkyl)cycloalkanone (III) which is then hydrolyzed and decarboxylated to afford the 2-(.omega.-carboxyalkyl)cycloalkanone (IV). This acid is then esterified with ethanol whereby the 2-(.omega.-carbethoxyalkyl)cycloalkanone (V) is obtained. The reaction conditions for carrying out the above sequence of reactions are well known in the art. The conversion of the cycloalkanone (V) to the enol acetate (VI) is effected by heating with acetic anhydride in the presence of p-toluenesulfonic acid. Preparation of the enol acetate (VI) usually requires heating for a period of from about eight to thirty-six hours. During this period, it is preferable to allow by-product acetic acid to distill out in order to force the reaction to completion. The bromination of the enol acetates (VI) to the 2-bromocycloalkanones (VII) is preferably carried out in a two phase system as follows. A solution of bromine in chloroform is added to a rapidly stirred mixture of a solution of the enol acetate (VI) in chloroform and an aqueous solution of an acid acceptor such as calcium carbonate or soda ash. This addition is carried out at 0.degree. -5.degree. C. over a period of about half an hour, stirring is continued for an additional period of about half an hour to a few hours, and the product (VII) is then isolated by standard procedures. The dehydrobromination of the 2-bromocycloalkanones (VII) is preferably carried out in dimethylformamide with a mixture of lithium bromide and lithium carbonate at the reflux temperature for a period of about 30 minutes to an hour or so. The so formed cycloalk-2-en-1-ones (VIII) are also isolated by standard procedures well known in the art. Substitution of X-(CH.sub.2).sub.m --C(R.sub.4).sub.2 --CH.sub.2 --CO.sub.2 C.sub.2 H.sub.5 for (II) in Flowsheet A and carrying through the sequence of transformations illustrated therein is productive of the following cycloalk-2-en-1-one (VIIIa): ##STR9## wherein X, n, m and R.sub.4 are as hereinabove defined.
The required cycloalk-2-en-1-one intermediates of general structure (XVI), wherein the side-chain has a lower alkyl group, fluorine atom or phenyl group alpha to the carbethoxy function, may be prepared in accordance with the following reaction scheme: ##STR10## wherein n, m and R.sub.5 are as hereinabove defined and G is a lower alkyl or aryl group. In accordance with this reaction scheme, the 2-(.omega.-carbethoxyalkyl)cycloalk-2-en-1-ones (IX) are converted to the corresponding 1-methoximino-2-(.omega.-carbethoxyalkyl)-2-cycloalkenes (X) by treatment with methoxyamine. With the ring carbonyl function thus blocked it is possible to effect a preferential reduction of the ester group by treatment with diisobutylaluminum hydride. The resulting alcohol (XI) is converted to a tosylate derivative (XII), which undergoes displacement on treatment with the sodium salt of a diethyl R.sub.5 -substituted malonate (XIII) to provide the disubstituted malonate derivatives (XIV). Hydrolysis and decarboxylation as well as concomittant cleavage of the methoximino blocking group provides the desired 2-(.omega.-carboxy-.omega.-R.sub.5 -substituted-alkyl)cycloalk-2-en-1-ones (XV), which are readily converted to the corresponding ester (XVI) by the usual procedure via the acid chloride and subsequent treatment with the appropriate alcohol in the presence of a tertiary amine.
The requisite 2-(.omega.-carbethoxy-.omega.-1-oxa-alkyl)cycloalk-2-en-1-ones (XXII) and 2-(.omega.-carbethoxy-.omega.-1-thia-alkyl)cycloalk-2-en-1-ones (XXVI) may be prepared in accordance with the reaction schemes of Flowsheet C, wherein n and m are as hereinbefore defined. ##STR11##
In accordance with the reaction scheme shown in Flowsheet C, for the preparation of the oxa derivative (XXII), an appropriate 2-(.omega.-carbethoxyalkyl)cycloalk-2-en-1-one (XVII) is converted to the corresponding methoxime (XVIII), the ester function of which is then preferentially reduced with diisobutylaluminum hydride to afford the methoxime alcohol (XIX). The alcohol (XIX) is converted on treatment with n-butyl lithium to the lithio alcoholate, which then is O-alkylated by reaction with ethyl bromoacetate to provide (XX). Hydrolysis with acetone-aqueous hydrochloric acid furnishes the deblocked keto-acid (XXI), which is then re-esterified with ethanol in the presence of p-toluenesulfonic acid to give the required 2-(.omega.-carbethoxy-.omega.-1-oxa-alkyl)cycloalk-2-en-1-one (XXII). O-Alkylation can also be accomplished by treatment of the lithio alcoholate of (XIX) with sodium or other metal salt of bromoacetic acid, in which case the free carboxylic acid corresponding to ester (XX) is obtained. Hydrolysis as for (XX) provides the keto acid (XXI).
The preparation of the thia derivative (XXVI), proceeds from the intermediate alcohol (XIX), which after conversion to the tosylate intermediate (XXIII) and reaction with the sodium salt of ethyl mercaptoacetate furnishes intermediate (XXIV). Deblocking of XXIV with acetone-aqueous hydrochloric acid provides the keto-acid (XXV), which on re-esterification with ethanol gives the required 2-(.omega.carbethoxy-.omega.-1-thia-alkyl)cycloalk-2-en-1-ones (XXVI).
Certain of the 11-deoxy-9-keto(or hydroxy)-prostanoic acid derivatives of this invention, as defined in the general formula on page 1 above, may be prepared from cycloalkenone (XXXI) and the triphenylmethoxy substituted 1-alkyne (XXVII) as depicted in Flowsheet D. In Flowsheet D, n, R.sub.3, R'.sub.3 and Z are as hereinabove defined; R'.sub.2 is a straight chain alkyl group having from 2 to 10 carbon atoms, a straight chain alkyl group having from 2 to 10 carbon atoms and substituted with one or two alkyl groups each having from one to three carbon atoms, a straight chain alkenyl methyl group having from two to nine carbon atoms, or a straight chain alkenyl methyl group having from two to nine carbon atoms and substituted with one or two alkyl groups having between them 2 to 5 carbon atoms; and R is a lower alkyl group. ##STR12##
In accordance with the reaction scheme of Flowsheet D, the triphenylmethoxy substituted 1-alkyne (XXVII) is treated with diisobutylaluminum hydride (XXVIII). This reaction of the 1-alkyne (XXVII) with diisobutylaluminum hydride (XXVIII) provides the alane (XXIX) containing the trans-double bond and is carried out in an inert solvent such as benzene, toluene, and the like at temperatures in the range of 40.degree.-60.degree. C. for several hours. It can also be carried out in a solvent such as tetrahydrofuran, usually in an approximate 2:1 mixture with benzene or hexane; in which case the reaction requires somewhat more vigorous conditions, usually treating at about 70.degree.-75.degree. C. for about eighteen hours. The subsequent reaction with methyl or n-butyl lithium (R-Li) is preferably carried out in a mixture of the above solvents with an ether-type solvent such as diethyl ether, dibutyl ether, tetrahydrofuran and the like. This reaction is rapid and is preferably carried out at 0.degree.-10.degree. C. with cooling. The conjugate 1,4-addition of the resulting alanate salt (XXX) to the cycloalk-2-en-1-one (XXXI) is preferably carried out at ambient temperatures for a period of 12 to 24 hours. This reaction is also best carried out in an ether-type solvent such as diethyl ether, dibutyl ether, tetrahydrofuran, and the like. The intermediate alanate-enolate adduct is then carefully hydrolyzed in situ with dilute hydrochloric acid with cooling, and the products (XXXII) are isolated in the usual manner well known in the art. Removal of the triphenylmethyl blocking group can then be accomplished by treating with weak acid. A preferred procedure involves heating at 45.degree. C. for 3.5 hours in a solvent system consisting of acetic acid:tetrahydrofuran:water in the proportion of 4:2:1. Saponification in the usual manner of the resulting alkyl ester (XXXIII, R.sub.3 .dbd.alkoxy) provides the corresponding carboxylic acid (XXXIII, R.sub.3 .dbd.OH).
All available evidence leads us to the conclusion that in the product (XXXIII) the two side-chains attached to C.sub.8 and C.sub.12 are trans to each other. However, we are not certain of the configurational relationship in product (XXXII) as it is obtained directly from the alanate process. These products may have the side-chains in a trans or cis relationship or they may be a mixture containing both the trans- and cis-isomers. This is indicated in the nomenclature of the compounds involved by the designation of 8.xi.. In order to ensure a trans-relationship in both (XXXII) and (XXXIII) these products can be submitted to conditions known in the literature to equilibrate the cis-8-iso-PGE.sub.1 to a mixture containing about 90% of the trans product. These conditions involve treatment with potassium acetate in aqueous methanol for 96 hours at room temperature.
The triphenylmethyl blocking group for the hydroxy function in (XXVII) etc. is an important feature of this process and other oxygen blocking groups, e.g., tetrahydropyranyl and alkyl, are not compatible with a clean cis-addition of diisobutyl aluminum hydride (XXVIII) to the alkyne (XXVII) to provide the desired trans-vinyl function. Alternative procedures for the preparation of novel lithio alanate reagents useful for the introduction of the .DELTA..sup.13 -trans 15-oxy .beta.-chain by conjugate 1,4-addition are illustrated in Flowsheet K further below.
The intermediates for the introduction of the .DELTA..sup.13 -15-hydroxy side-chain are an integral part of this invention and they may be represented by the following general formulae (A), (B), (C), (D) and (E) wherein R'.sub.2 is as hereinabove defined, R is a lower alkyl group, not necessarily the same for each use, and R' is an alkyl group having from one to ten carbon atoms not necessarily the same for each use, W.sub.1 is lower alkoxy, triphenylmethyl, or a triphenylmethyl group in which one or two of the phenyl rings is substituted with a lower alkoxy group; W.sub.2 is lower alkoxy, triphenylmethyl, a triphenylmethyl group in which one or two of the phenyl rings is substituted with a lower alkoxy group, tetrahydropyranyl, .alpha.-(lower alkoxy) substituted lower alkyl, t-butyl, or a tri-(lower alkyl)silyl group; X.sub.1 is iodo or bromo; s is an integer having the value of one to three inclusive, and t is an integer having the value of one to three inclusive, with the proviso that the sum of s and t must be equal to four. ##STR13##
The alanate conjugate addition procedure is also useful for the synthesis of prostaglandin E.sub.1 (XL) as illustrated in Flowsheet E. This reaction sequence is carried out in the same manner as described for the sequence in Flowsheet D. It is to be noted that the introduction of the .DELTA..sup.13 -15-oxy chain proceeds trans to the 11-oxy function. For this synthesis, it is best to use the tetrahydropyranyl or trialkylsilyl esters, since these esters can be hydrolyzed under conditions compatible with the stability of the .beta.-ketol feature of prostaglandin E. Alkyl esters would be hydrolyzed by fermentation with Baker's Yeast. The tetrahydropyranyl or trialkylsilyl, and triphenylmethoxy blocking groups are removed by mild acid treatment, for example with acetic acid:tetrahydrofuran:water (4:2:1) as described hereinabove. Application of the lithio alanate conjugate addition process to the synthesis of prostaglandins E.sub.2 and E.sub.3 is described below in connection with Flowsheet H. ##STR14##
The 13-dihydro derivatives (C.sub.13 -C.sub.14 is ethylene) of this invention can be prepared by reduction of the .DELTA..sup.13 function in the corresponding 13-prostenoic acids or esters. This reduction can be accomplished by hydrogenation. However this procedure is not cleanly applicable in the presence of other double bonds in the molecule. In the latter instance the 13-dihydro derivatives are preparable via conjugate addition of a Grignard derivative (XLII) to cycloalkenone (XLI) in the presence of a catalyst such as the tributylphosphine cuprous iodide complex as set forth in Flowsheet F, wherein n, Z, R.sub.2 and R'.sub.3 are as hereinabove defined; Q is a blocking group; and X is chlorine, bromine or iodine, preferably bromine or iodine. The blocking group (Q) for the hydroxyl function in (XLII) can be any group stable to the Grignard reagent and which can later be removed by chemical treatment (e.g., mild hydrolysis or catalytic hydrogenolysis in the absence of carbon to carbon double bonds elsewhere in the molecule) to which the remainder of the molecule is stable. Suitable blocking groups, therefore, may be, for example, benzyl, diphenylmethyl, triphenylmethyl, tetrahydropyranyl, or a moiety of the formula: ##STR15## wherein R.sub.11 is hydrogen, methyl or ethyl. Among the above-described blocking groups, we have found tert-butyl to be particularly convenient and useful. ##STR16##
In accordance with the above reaction scheme, the conjugate 1,4-addition of a 3-(substituted hydroxy)alkyl or alkenyl magnesium halide (XLII) to a cycloalk-2-en-1-one (XLI) is carried out in the presence of a catalyst. In general, Grignard reactions with conjugated ketones provide 1,2-addition products; conjugate 1,4-addition is usually accomplished when the reaction is carried out in the presence of a cuprous chloride or cuprous acetate catalyst. It is therefore most unexpected that the reaction of the cycloalkenone (XLI) with a Grignard reagent (XLII) in the presence of either of the aforementioned catalysts does not give appreciable amounts of the desired 1,4-conjugate addition products. The novel feature of our process is provided by the use, as a catalyst, of a cuprous halide complex with a trisubstituted phosphine, a trialkyl phosphonate, a tertiary amine or a heterocycle containing a basic nitrogen (e.g., pyridine). We have found it preferable to use tributylphosphine-cuprous iodide complex; (C.sub.4 H.sub.9).sub.3 P.CuI. The reaction is best carried out in the usual way in an ether-type solvent such as diethyl ether, dibutyl ether, tetrahydrofuran, and the like, at room temperature for a period of time of from two to eighteen hours. The intermediate magnesium halide-enolate adduct is then hydrolyzed in situ, preferably with ammonium chloride, at room temperature and the product (XLIII) is isolated in the usual manner well known in the art.
When the blocking group is a tertiary alkyl moiety such as tert-butyl, deblocking of (XLIII) to afford (XLIV) is conveniently effected by treatment with glacial trifluoroacetic acid at from -5.degree. C. to 10.degree. C. for a period of one to three hours. Since this procedure may lead to partial trifluoroacetylation of the free hydroxy function, it is preferably followed by treatment with aqueous ammonia (about 1.0 N concentration) for about 15 minutes at ambient temperatures. When the blocking group is tetrahydropyranyl, its removal is readily effected with dilute acid. When the blocking group is a moiety such as benzyl, diphenylmethyl or triphenylmethyl, deblocking of (XLIII) is conveniently effected by catalytic hydrogenolysis, procedure for which are well known in the art. In the instance of triphenylmethyl, deblocking is preferably effected by treating with acetic acid:tetrahydrofuran:water (4:2:1) at about 45.degree. C. for about 3.5 hours.
Mild acid treatment results in hydrolysis of the tetrahydropyranyl esters; alkyl esters can be hydrolyzed by the usual saponification techniques.
When the cycloalkanone esters (XLIII) are formed by quenching of the reaction mixture with aqueous ammonium chloride solution, the relative stereochemical relationship of the two side-chains is not known with certainty. Therefore, the bond linking the Grignard-derived side-chain to the cycloalkyl ring is indicated by a .about. bond in (XLIII). However, in any case, the subsequent deblocking and ester hydrolysis procedures ensure the development, at least in predominant proportion, of the thermodynamically favored trans-relationship between the two side-chains, as is depicted in structure (XLIV) of the reaction scheme.
An alternative method for the introduction of the .DELTA..sup.13 -15-hydroxy side-chain involves 1,4-conjugate addition to cycloalkenone (LV) of a vinyl Grignard reagent [(LIII)+(LIV)] in the presence of a catalyst such as the tributylphosphine cuprous iodide complex followed by deblocking. From this process, in addition to the product (LVIII) containing the C.sub.13 -C.sub.14 moiety as a trans-vinylene function there also is obtained the corresponding product (LIX) in which the C.sub.13 -C.sub.14 moiety is a cis-vinylene function. These novel cis-.DELTA..sup.13 derivatives are also embraced within the scope of this invention. The reaction sequence for the "vinyl" Grignard process is illustrated in flowsheet G, which follows, and in which W.sub.2, n, Z, R.sub.3 and R'.sub.3 are as hereinabove defined, and R".sub.2 is a straight chain alkyl group having from 2 to 10 carbon atoms, or a straight chain alkyl group having from 2 to 10 carbon atoms and substituted with one or two alkyl groups having from one to three carbon atoms. ##STR17##
In accord with the reaction sequence of Flowsheet G the vinyl Grignard reagent (LIII+LIV), is prepared under an inert atmosphere in a relatively limited amount of anhydrous tetrahydrofuran. More vigorous conditions (e.g., heating in an oil bath at 70.degree.-80.degree. C., one hour), for the formation of the Grignard reagent (LIII+LIV) favors the proportion of .DELTA..sup.13 -cis isomer (LIX) in the product of conjugate addition. Milder conditions (for example 35.degree.-47.degree. C., one hour) favors the proportion of .DELTA..sup.13 -trans isomer (LVIII) in the final product.
Conjugate addition of the vinyl Grignard reagent mixture [(LIII)+(LIV)] to cycloalkenone (LV) is then preferably carried out by addition of the Grignard to the cycloalkenone dissolved in an ether type solvent, e.g., diethylether, containing a catalyst such as the tributylphosphine-cuprous iodide complex at a temperature of about 0.degree. C. After a period of about thirty minutes to three hours the reaction mixture is poured onto aqueous concentrated ammonium chloride solution to give (LVI)+(LVII). As explained hereinabove, at this stage the relationship of the two side-chains to each other is not determined. In any event, deblocking the 15-hydroxy function with weak acid (which procedure also hydrolyzes trialkylsilyl or tetrahydropyranyl esters) provides the product (LVIII) and (LIX) in which the chains are trans to each other. In the instance of alkyl esters, saponification provides the corresponding carboxylic acids. The .DELTA..sup.13 -cis and .DELTA..sup.13 -trans-isomers can be separated from each other by the usual techniques of chromatography; particularly useful is liquid-liquid partition chromatography.
The precursor 3-hydroxy-1-trans-alkenyl bromides (LI) can be prepared, as illustrated in Flowsheet G, by condensation of acetylene (XLV) with an acid chloride (XLVI) in the presence of aluminum trichloride. The resulting 3-oxo-1-chloro-trans-1-alkylene (XLVII) is then converted to the corresponding 1-bromo derivative (XLVIII), by reaction with excess lithium bromide. This reaction is preferably carried out in ketone solvents, such as 2-pentanone or acetone. Reduction of the 3-keto function in (XLVIII), with for example, sodium borohydride provides the alcohol (LI). The alcohol function is then blocked to give (LII). Alternatively, the 3-oxo vinyl bromide (XLVIII) can be prepared directly from the acyl bromide (L) and acetylene (XLIX) in the presence of aluminum tribromide, preferably in ethylene dibromide.
The "vinyl Grignard" procedure outlined in Flowsheet G represents a novel, useful and convenient procedure for the synthesis of 13-prostenoic acids and the novel Grignard reagents represented by formulae (LIII) and (LIV) are to be considered as embraced within the scope of this invention.
The "vinyl Grignard" technique can also be applied to a useful synthesis of prostaglandin E.sub.1 and the novel .DELTA..sup.13 -cis-prostaglandin-E.sub.1 as illustrated in Flowsheet H, below. Thus, treatment of cyclopentenone (LX) with Grignard [(LXI+(LXII)] in accordance with the considerations discussed hereinabove, provides the conjugate addition products (LXIII) plus (LXIV), mild acid hydrolysis of which furnishes prostaglandin E.sub.1 (LXV) and .DELTA..sup.13 -cis prostaglandin E.sub.1 (LXVI), separable by chromatography. ##STR18##
The preparation of the cycloalkenone intermediates (LXXVI, LXXVII) bearing a cis double bond in the carboxylic acid side chain can be accomplished by the sequence illustrated in Flowsheet I, which follows and in which n and p are as hereinabove defined. ##STR19##
In the above Flowsheet I, the sequence wherein a 2-carbalkoxycycloalkanone (LXVII) is transformed to a 2-(.beta.-hydroxyethyl)cycloalk-2-en-1-one (LXXIII) is carried out in the manner described in Flowsheet A. Methyl ether cleavage of the corresponding 2-(.beta.-methoxymethyl)cycloalkenone is achieved by treating with boron tribromide. Oxidation of the alcohol (LXXIII) with Collins reagent [chromium trioxide-pyridine complex in methylene chloride under anhydrous conditions; J. C. Collins, W. W. Hess, and F. J. Frank, Tetrahedron Letters, 3363 (1968)] provides the aldehyde (LXXIV), which is then treated in anhydrous dimethylsulfoxide with the ylid (LXXV) prepared from an (.omega.-carboxyalkyl)triphenyl phosphonium bromide and sodium hydride. The use of dimethylsulfoxide as a solvent for this reaction leads to the predominant formation of the desired cis double bond derivative (LXXVI). The acid function in (LXXVI) can be esterified in the usual fashion; with diazomethane, the methyl ester (LXXVII) is obtained.
Cyclopentenones such as (LXXVI wherein n-1) may also be prepared by the sequence illustrated in Flowsheet J, which follows and in which p is as hereinabove defined. ##STR20##
In Flowsheet J above the bicyclic hemiacetal (LXXVIII) [P. A. Grieco, Journ. Org. Chem., 37, 2363 (1972)] is treated with ylid (LXXIX) to give the 1-hydroxy-3-cyclopentene (LXXX). Oxidation with Jones reagent gives the corresponding ketone (LXXXI), which on base treatment furnishes the required cyclopentenone (LXXXII), which can then be esterified in the usual manner.
Certain of the intermediates illustrated in Flowsheets I and J, in particular the compounds of formulae (LXXI), (LXXII), (LXXIII), (LXXIV), (LXXVI) (LXXVII) (and related esters), (LXXX) and (LXXXI) are novel and useful compounds and are embraced within the scope of this invention.
Alternative procedures for the preparation of the alanate intermediates to that discussed in connection with Flowsheet D above are illustrated below in Flowsheet K, wherein R', R'.sub.2, R".sub.2 and W.sub.2 are as hereinabove defined. ##STR21##
In accordance with the sequence of Flowsheet K above the 1-iodo-trans-1-alkenyl-3-oxo derivative (LXXXIV) is prepared by iodide interchange, preferably in acetone or similar ketone, from the corresponding chloride (LXXXIII), the preparation of which is described in connection with Flowsheet G above. Reduction of (LXXXIV) to the alcohol (LXXXVI) can be accomplished in the usual manner with sodium borohydride. The hydroxy function is then blocked to give (LXXXV, R'.sub.2 -R".sub.2). Treatment of the acetylene, ##STR22## with one equivalent of disiamylborane (prepared in situ from diborane and 2-methyl-2-butene) and then with excess anhydrous trimethylamine oxide followed by treatment with an aqueous solution of excess sodium hydroxide and a tetrahydrofuran solution of excess iodine is also productive of (LXXXV). Treatment of the trans-1-alkenyl iodide (LXXXV) at low temperatures, preferably at about -30.degree. C. to -78.degree. C., in an inert solvent, e.g., hexane or toluene, with an alkyl lithium, e.g., butyl lithium, provides the trans-1-alkenyl lithium reagent (LXXXVII). Treatment of this lithio derivative with a tri-alkyl aluminum furnishes the trans-1-alkenyl trialkyl alanate (LXXXVIII). Treatment of a dialkyl aluminum chloride with two molar equivalents of lithio reagent (LXXXVII) gives the bis(trans-1-alkenyl)dialkyl alanate (LXXXIX) and treatment of an alkylaluminum dichloride with three molar equivalents of lithio reagent (LXXXVII) affords the tris(trans-1-alkenyl)alkyl alanate (XC).
Each of the three types of alanates, (LXXXVIII), (LXXXIX) and (XC), can be utilized for 1,4-conjugate addition reactions as described hereinabove in connection with Flowsheets D and E above. Thus, substitution of (LXXXVIII), (LXXXIX) or (XC) for alanate (XXX) in Flowsheet D will provide the indicated products of the Flowsheet. Similarly, substitution of (LXXXVIII), (LXXXIX) or (XC) in which R'.sub.2 is n-pentyl for alanate (XXXVII) in Flowsheet E provides prostaglandins E.sub.1. In general the mono alkenyl alanate (LXXXVIII) is preferred because it is more economical in the use of vinyl halide.
With regard to the cycloakenones of Flowsheets D, E, F, G and H it should be noted that the blocking groups for the 4-hydroxy function as well as for the carboxylic acid may also be a tri-alkylsilyl group, e.g., trimethylsilyl, dimethyl-t-butylsilyl or dimethylisopropylsilyl. Cyclopentenones blocked in this manner are illustrated below in formula (XCI) and (XCII) wherein m, n, Z and R' (not necessarily the same for each use) are as hereinabove defined. ##STR23##
All the novel products of this invention exclusive of certain intermediates bear a hydroxy or oxy function substituted at or at what ultimately becomes the C.sub.18 atom of the product prostanoic acids and esters. Thus in at least most instances a 15-"normal" and a 15-"epi" racemate is obtained in at least near equal proportions. Each of the racemates contains equal amounts of the enantiomer wherein C.sub.18 is in the S configuration and the enantiomer wherein it is in the R configuration. The racemates are separable from each other by the usual techniques of chromatography. Also, resolution in the usual way of the .beta.-chain precursor [for example, the resolution of 3-hydroxy-1-octyne is described in the literature [see R. Pappo, P. Collins and C. Jung. Ann. N.Y. Acad. of Science, 180 (Prostaglandins), 64(1971); J. Fried et al., ibid, p. 381]. Resolution prior to the conjugate addition operation will provide the diastereomers wherein the C.sub.15 atom is either in the 15(S) or 15(R) configuration, as desired. Separation of the diastereomers so obtained, for example, by chromatography, will give the fully resolved (d and 1) products provided there are no asymmetric carbon atoms other than at C.sub.8 and C.sub.12. The presence of other asymmetric sites requires additional resolution steps in order to obtain a single atipode. The compounds of this invention embrace all possible optical isomers.
The 11-deoxy-9-keto derivatives (XCIV) of this invention can be converted to the corresponding 9-hydroxy derivatives. If this conversion is effected with sodium borohydride, the product is a mixture of 9.alpha.-and 9.beta.-hydroxy derivatives (XCIII) and (XCV) as set forth in the following reaction scheme: ##STR24## wherein R.sub.2, R.sub.3, R.sub.6, R.sub.7, Z, n and --C.sub.13 -C.sub.14 -- are as hereinabove defined. In general, when the reaction is carried out with lithium perhydro-9b-boraphenalyl hydride [H. C. Brown and W. C. Dickason, Journ. Amer. Chem. Soc., 92, 709 (1970)] the product is at least predominantly the 9a-hydroxy derivative (XCIII), wherein the 9-hydroxy group is cis to the side-chain attached to C.sub.8.
In accordance with accepted convention, an a-substituent at the 8-, 9-, or 12-positions is behind the plane of the paper whereas a .beta.-substituent at these positions is in front of the plane of the paper. This is usually represented by a ---bond for an a-substitutent, a--bond for a .beta.-substituent, and a .about..about.bond where both are indicated. Thus, the 9-hydroxy derivatives may be variously represented as follows: ##STR25##
A useful procedure for the introduction of the 15-lower alkyl group (R.sub.6) is illustrated by the sequences of Flowsheet M, which follows. ##STR26##
In Flowsheet M above n, Z, R.sub.2, R.sub.7 and R.sub.6 are as hereinabove defined. In the sequence depicted in Flowsheet M the 9,15-diol (XCVI) is treated with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) (XCVII), which preferentially oxidizes the allylic alcohol function at C.sub.15 to give the 15-ketone (XCVIII). Blocking of the remaining hydroxy function as a trimethylsilyl ether gives (IC) which is reacted with the alkyl Grignard R.sub.e MgI, to give the 15-alkyl-15-hydroxy derivative (CI). Hydrolysis of the silyl ether blocking group then gives the diol ester (C), saponification of which gives (CII). Oxidation of the secondary 9-hydroxy function in (C) provides the 15-alkyl-9-oxo ester (CIII), saponification of which furnishes (CIV). (A similar sequence can be effected with the .DELTA..sup.13 -cis-series.)
The processes of this invention are also useful for the preparation of prostaglandin E.sub.2 and prostaglandin E.sub.3 and thus also PGF.sub.3a and PGF.sub.3a by reduction, for example with lithium perhydro-9b-boraphenalyl hydride. The 4-hydroxycyclopentenone intermediate (CXI) required for these syntheses is prepared in accordance with the procedure illustrated in Flowsheet N which follows and in which is also shown the transformation of this compound to prostaglandins E.sub.2 and E.sub.3. In Flowsheet N, J is an appropriate blocking group for the hydroxy and ester function in (CXI) which is compatible with the conjugate addition reaction and also is ultimately removable by acid-catalyzed hydrolysis or other techniques which will not disrupt the sensitive 11-oxy-9-keto system in the products (CXIII), (CXV), (CXVIII) and (CXVII). Particularly useful for this purpose are the tetrahydropyranyl group and various trialkylsilyl groups (e.g., dimethylisopropylsilyl, trimethylsilyl, dimethyl-t-butylsilyl and the like. ##STR27##
In accordance with the above reaction scheme the 3,4-epoxylactol (CV) [E. J. Corey and R. Noyori, Tetrahedron Letters, 311 (1979)] is treated with the ylide (CVI) to give the 3,4-epoxycyclopentanol (CVII) bearing the .alpha.-chain of the prostaglandin 2 series. Oxidation (for example with H.sub.2 CrO.sub.4.H.sub.2 SO.sub.4 -ether or Jones reagent) of (CVII) provides the epoxy ketone (CVIII), mild base treatment of which results in the initial formation of the 4-hydroxycyclopent-2-en-1-one (CXI) and the isomeric 3-hydroxycyclopent-4-en-1-one (CX) as a mixture. Further treatment of this mixture with diluent base under mild conditions (preferably pH 10.3-10.6 for 24 hours) results in the isomerization of the 3-hydroxy isomer (CX) to the desired (CXI). We believe that the transformation of the epoxy ketone (CVIII) to the hydroxycyclopentenones (CX) and (CXI) and the isomerization of (CX) to (CXI) may take place through the intermediacy of the 3,4-diol (CIX). It is also conceivable that isomerization of (CX) to (CXI) procedes via the epoxy derivative (CVIII) or the corresponding .alpha.-epoxide (CXIb); it is further conceivable that (CVIII) procedes to (CX) and (CXI) directly without the intermediacy of (CIX). Another possible intermediate for the isomerization of (CX) to (CXI) is the corresponding diene (CXIa). The preparation of (CXI) is also possible via the .alpha.-epoxide series from (CXIc) via the .alpha.-epoxide corresponding to (CVII) and (CVIII) such as (CXIb) or via a mixture of the .alpha. and .beta. epoxides. In practice, it is most convenient to utilize a mixture of .alpha.- and .beta.-epoxides (CXIc and CV). The hydroxy and acid function in the 4-hydroxycyclopentenones (CXI) are then appropriately blocked to give (CXII). Appropriate blocking groups are tetrahydropyranyl, trimethylsilyl, dimethyl-isopropylsilyl, dimethyl-t-butylsilyl and the like. Treatment of (CXII) with the lithio alanate (CXIV) or its equivalent (see the discussion hereinabove for Flowsheets K and E) gives the conjugate addition product (CXIII) in which the configuration at C.sub.8 is undetermined. Mild acid treatment, for example with acetic acid:tetrahydrofuran:water, (4:2:1), of (CXIII) results in the removal of blocking groups, and if necessary equilibration to the all-trans configuration, to give prostaglandin E.sub.2 (CXV). Similarly treatment of (CXII) with the lithio alanate (CXVI) gives prostaglandin E.sub.2 (CXVII).
Substitution in Flowsheet N, of ylide (CXIX), wherein p is as hereinabove defined, for the ylide (CVI) provides, by transformations analogous to those described in Flowsheet N [(CV) to (CXI) and (CXII)], the 4-hydroxycyclopent-2-en-1-ones (CXX) and their blocked ether-esters (CXXI). These novel and useful intermediates are a part of the present invention. ##STR28##
The 8.beta.-lower alkyl group (R.sub.7 ') is introduced as illustrated in Flowsheet O below via the bromomagnesium enolate (CXXV). This novel and useful intermediate is obtained by conjugate addition of the 1-alkenyl Grignard reagent [(CXXIII)+(CXXIV)], preferably prepared at about 35.degree. C., to the cycloalkenone (CXXII) in the presence of a catalyst such as the tri-n-butylphosphine cuprous iodide complex as described hereinabove in connection with Flowsheets G and H. It is also possible to utilize for these purposes in an analogous manner the magnesio enolate (CXXVIII) obtained by conjugate addition of Grignard (XLII) to cycloalkenone (XLI) as described hereinabove in connection with Flowsheet F, in which case the 13,14-dihydro derivative of this invention are obtained. In Flowsheet 0 below, n, Z, R.sub.3, R'.sub.3, R'.sub.2, W.sub.2, Q and X are as hereinabove defined and R'.sub.7 is an alkyl group having up to 3 carbon atoms. When the magnesio enolate (CXXV) is treated with a lower alkyl halide, e.g., methyl iodide, it undergoes alkylation at the 8.beta.-site providing, after deblocking of the 15-oxy group in intermediate (CXXVI), the 8.beta.-alkyl derivative (CXXVII). In the instance of alkyl esters, saponification gives the corresponding carboxylic acids (CXXVII, R.sub.3 .dbd.OH). The compounds corresponding to (CXXVII) wherein C.sub.13 -C.sub.14 is a cis-vinylene double bond are preferably prepared by utilizing the vinyl Grignard reagent prepared at temperatures in the range of 70.degree.-75.degree. C., as discussed hereinabove (Flowsheets G and H).
Also obtained from the alkylation of (CXXV) is the 8.alpha.-alkyl-8-iso derivative corresponding to (CXXVI), which after deblocking provides the 8.alpha.-alkyl-8-iso-products (CXXIX). Usually the 8.alpha.-product is formed to a significantly lesser extent than the 8.beta.-product (CXXVI). The 8.alpha. and 8.beta. products are separable from each other by the usual techniques of chromatography. ##STR29##
Application of the 8-alkylation process to the 11-oxy series provides the novel compounds of formula (CXXX), wherein R.sub.1, R.sub.2, R.sub.6, Y and C.sub.13 -C.sub.14 are as hereinabove defined and wherein R'.sub.7 is an alkyl group having up to 3 carbon atoms, R.sub.8 is selected from the group consisting of hydrogen, lower alkanoyl, tetrahydropyranyl and tri-lower alkylsilyl groups, R.sub.9 is selected from the group consisting of hydroxy, alkoxy having from 1 to 12 carbon atoms, tetrahydropyranyloxy and tri-lower alkyl silyloxy groups, Z.sub.2 is a divalent radical selected from the group consisting of those of the formulae: ##STR30## wherein m, p, R.sub.4 and R.sub.5 are as hereinabove defined; and the moiety ##STR31## also be the divalent radical ##STR32## with the proviso that only one unsaturated bond can be directly adjacent to C.sub.15 ; and with the second proviso that when R.sub.4 is alkyl then R.sub.1 is hydrogen; and with the third proviso that the groups attached to C.sub.8 may be in the 8.beta.-alkyl (8-iso) configuration: ##STR33##
The novel compounds of formula (CXXX) are also embraced by this invention. The preparation of these compounds may be illustrated by the reaction sequence of Flowsheet P below, wherein R.sub.9 Z.sub.2, W.sub.2, R".sub.2, R'.sub.7 and R.sub.6 are as hereinabove defined and R'.sub.8 has all the possibilities defined above for R.sub.8 except that it is not hydrogen. ##STR34##
In accordance with the sequence of Flowsheet P above, treatment of the ether-ester 4-oxycyclopentenone (CXXXI) with the 1-alkylene Grignard reagents [(CXXIII)+(CXXIV)] (see Flowsheet O) gives the bromomagnesio enolate (CXXXII). This operation also results in the introduction of the trans C.sub.13 -C.sub.14 double bond (as shown in CXXXII), as well as the corresponding compound with the cis-double bond. The trans bond is favored when the Grignard is prepared at lower temperatures, about 35.degree. C.; the cis-bond at higher temperatures, about 70.degree.-75.degree. C. This point is more fully discussed above in connection with Flowsheets G and H. The magnesio enolate (CXXXII) is a key intermediate and when it is treated with a lower alkyl halide, e.g. methyliodide, it undergoes alkylation to give the 8.beta.-lower alkyl derivative (CXXXIII). Deblocking of the 15-hydroxy blocking group (e.g., triphenylmethyl), and of the 11-hydroxy tetrahydropyranyl or trialkylsilyl ether blocking groups as well as of the tetrahydropyranyl or trialkyl silyl esters is accomplished under mild acid conditions, e.g. heating at 45.degree. C. for 3.5 hours in a solvent system consisting of acetic acid:tetrahydrofuran:water (4:2:1). This procedure provides (CXXXV). The compounds of structure (CXXXV) or (CXXXIII) can be converted to 8.beta.-alkyl prostaglandins of the A class (CXXXIV) by treatment with acid or base, a preferred procedure involves treatment in tetrahydrofuran:water (2:1) solvent 0.5 N in hydrochloric acid for about seventy hours at ambient temperatures.
The novel compounds of this invention represented by formula (CXXXIV) and related compounds are particularly interesting sunce they represent "stabilized" prostaglandin A types, which cannot rearrange to the biologically relatively inactive prostaglandins of the B series.
Utilization of Grignard (XLII) (see Flowsheet F, hereinabove) in the sequence of Flowsheet P provides the compounds of (CXXX) wherein C.sub.13 -C.sub.14 is ethylene. Provided there are no other double bonds in the molecule these substances can also be obtained by catalytic hydrogenation of the compounds represented by formula (CXXXV).
The alkylation process described above for Flowsheets O and P also gives the corresponding 8.alpha.-alkyl derivatives which are separable from the 8.beta.-alkyl isomer by chromatography. Thus, for example, in Flowsheet O treatment of enolate (CXXV) with R'.sub.7 I gives not only the 8.beta.-alkyl product (CXXVI) as shown, but there also is obtained the 8.alpha.-alkyl derivative (CXXXVI) shown below. In Flowsheet P, alkylation of enolate (CXXXII) also provides, in addition to (CXXXIII) shown, the 8.alpha.-alkyl-8-iso product (CXXXVII), shown below. These 8.alpha.-alkyl-8-iso derivatives can be deblocked and carried through the same series of transformation shown for the 8.beta.-derivatives (CXXVI) and (CXXXIII) in Flowsheets O and P, respectively. These novel 8.alpha.-alkyl-8-iso derivatives and their transformation products are also a part of this invention, as are the key intermediate enolates represented by structures (CXXV) and (CXXXII). ##STR35##

Certain of the novel compounds of this invention possess utility as intermediates for the preparation of other of the novel compounds of this invention.
The compounds of this invention provide protection against the ulcerogenic properties of indomethacin. This assay was carried out in the following manner.
Rats were starved for 48 hours (water was given ad libitum). Indomethacin (20 mg./kg. of body weight) was administered by the subutaneous route and one-half the dose of the test compound was administered by gavage at the same time. After three hours, the second half of the test compound was administered also by Gavage. Five hours after the administration of indomethacin the animals were decapitated and the stomachs removed. The stomachs were washed with distilled water, blotted on gauze, cut along the larger curvature, and the contents rinsed with distilled water. The stomachs were spread out, pinned on a cork and visualized under magnifying glass for ulcers. The criteria for scoring of ulcers was as previously reported. [Abdel-Galil et al. Brit. J. Pharmac. Chemotherapy 33:1-14 (1968)].

Control animals treated with indomethacin but not test compound consistently give scores of about 3.0-3.5. Control animals treated with neither indomethacin nor test compound give scores of about 0.5-0.8. The results obtained in this assay with typical compounds of the present invention are set forth in Table 1 below. Compounds producing a score of 2.5 or lower are considered to be active.

The novel compounds of the present invention are also effective inhibitors of gastric acid secretion and of ulcer development in experimental animals, and thus are potentially valuable as agents for the control of gastric acid secretion and of gastric erosion and as anti-ulcer agents. Gastric acid secretion inhibitory action is usually measured by the "Shay rat" procedure .sup.(1,2) with some modifications as follows.
The rats (male, CFE strain) were starved for 48 hours (water was given ad libitum) to permit evacuation of stomach contents. On the morning of the experiment, under ether anesthesia, the abdominal region was shaved and a midline incision (1-11/2") was made with a scapel. With the help of a closed curved hemostate the duodenum was picked up. Upon getting the duodenum into view, fingers were used to pull the stomach through the opening, the stomach was then gently manipulated with fingers to rid the stomach of air and residual matter which were pushed through the pylorus. Two-5 inch sutures were drawn under the pyloric-duodenal puncture. A ligature, at the juncture was formed with one of the threads. The second ligature was also formed but not tightened.
The test compound or the vehicle, usually 1 ml./mg. body weight, were injected into the duodenum as close as possible to the first ligature. After injection the second ligature was tightened below the injection site to minimize leakage. The stomach was placed back through the opening into the abdominal cavity, the area of incision was washed with saline and the incision was closed with autoclips. (Occasionally, instead of an intraduodenal injection, animals were dosed by the oral or subcutaneous route. In the latter case, dosing was done thirty to sixty minutes before the operation.)
Three hours later, the rats were decapitated and exanguinated, taking care that blood did not drain into the estophagus. The abdominal cavity was exposed by cutting with scissors and the esophagus close to the stomach was clamped off with a hemostat, the stomach was removed by cutting above the hemostat (the esophagus was cut) and between the two sutures. Extraneous tissue was removed, the stomach washed with saline and blotted on gauze. A slit was carefully made in the stomach which was held over a funnel and the contents were collected in a centrifuge tube. The stomach was further cut along the outside edge and turned inside out. Two ml. H.sub.2 O were used to wash the stomach contents into the respective centrifuged tube. The combined stomach contents and wash were then centrifuged out for 10 minutes in the International Size 2 Centrifuge (setting at 30). The supernatant was collected, volume measured and recorded, 2 drops of a phenolphthalein indicator (1% in 95% ethanol) were added and the solution was titrated with 0.02 N NaOH (or with 0.04 N NaOH when large volumes of stomach contents were encountered) to pH 8.4 (because of usual coloring of the stomach contents, phenolphthalein was only used to permit visual indication that the end point was near) and the amount of acid present was calculated.
Compounds inducing inhibition of gastric acid secretion of 20% or more were considered active. In a representative operation, and merely by way of illustration, the results obtained with this assay with a typical compound of the present invention are given in Table 2, below.

In addition, all possible antipodes resulting from asymetry at C.sub.8, C.sub.12 and elsewhere in the prostenoic acid molecule are included.

EXAMPLE 257
Preparation of ethyl 9.alpha.,.beta.,15-dihydroxy-13-trans-prostenoate
A solution containing 3 g. of ethyl 9-oxo-15-hydroxy-13-trans-prostenoate (Example 121) in 120 ml. of absolute alcohol containing 115 mg. of sodium borohydride is stirred at ambient temperature for 18 hours. The solution is poured into 300 ml. of saturated sodium chloride solution and the oily precipitate is extracted with ether. The ether is washed with saturated sodium chloride solution, dried with anhydrous magnesium sulfate and taken to dryness to give subject product as an oil; .lambda.max. 2195, 5178, 8.45.mu.; the product is a mixture of 9.alpha.- and 9.beta.-hydroxy derivatives.
EXAMPLES 258-374
Treatment of the designated 9-oxo-15-triphenylmethoxy derivatives listed in the table below, with glacial acetic acid-tetrahydropyran-water (4:2:1) in the manner described in Example 121 is productive of the corresponding 15-hydroxy derivatives of the table. This acid treatment also ensures a trans-relationship between the two side-chains attached to C.sub.8 and C.sub.12.

EXAMPLE 1082
A solution of methyl 9-oxo-15-hydroxy-5-cis,13-trans,17-cis-prostatrienoate (Example 374) in tetrahydrofuran is added to 1.1 equivalent of lithium perhydro-9b-boraphenyalyl hydride in tetrahydrofuran at -78.degree. C. After 30 minutes equal volumes of 5% aqueous sodium carbonate and 30% aqueous hydrogen peroxide is added, and the solution is stirred 15 minutes. The solution is diluted with water and extracted with ether. The organic phase is dried (magnesium sulfate) and concentrated in vacuo to give methyl 9.alpha.,15.alpha.-dihydroxy-5-cis,13-trans,17-cis-prostatrienoate, contaminated with methyl 9.beta.,15.alpha.-dihydroxy-5cis,13trans,17cis-prostatienoate. The crude mixture of esters is dissolved in methylene chloride and added to a refluxing solution of 1.2 equivalents of 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in methylene chloride. After 5 hours, the solution is cooled and filtered. The filtrate is diluted with two volumes of ether, extracted with 5% aqueous sodium carbonate and dried with magnesium sulfate. The solution is concentrated in vacuo to give methyl 9.alpha. -hydroxy-15-oxo-5cis-13-trans, 17cis-prostatrienoate and 9.beta.-hydroxy-15-oxo-5cis, 13trans,17cis-prostatrienoate. The crude material is dissolved in benzene and 1.2 equivalents each of triethylamine and trimethylsilyl chloride is added. The triethylamine hydrochloride is removed by filtration and the solution is concentrated in vacuo to give methyl 9.alpha.-trimethylsiloxy-15-keto-5cis,13trans,17cis-prostatrienoate and the corresponding 9.beta.-trimethylsiloxy derivative.
The siloxy derivatives are dissolved in ether at 0.degree. C. and 1.05 equivalents of methyl magnesium bromide in ether is added. After the reaction is complete, the solution is poured into saturated aqueous ammonium chloride and extracted with ether. The ether is dried and concentrated in vacuo to give methyl 9.alpha.-trimethylsiloxy-15.alpha.-hydroxy-15.beta.-methyl-5cis,13trans,17cis-prostatrienoate, and methyl 9.alpha.-trimethylsiloxy-15.beta.-hydroxy-15.alpha.-methyl-5cis,13trans,17cis-prostatrienoate, methyl 9.beta.-trimethylsiloxy-15.alpha.-hydroxy-15.beta.-methyl-5cis,13trans,17cis-prostatrienoate, and methyl 9.beta.-trimethylsiloxy-15.beta.-hydroxy-15.alpha.-methyl 5cis,13trans,17-'cis-prostatrienoate. Hydrolysis of the siloxy functions of each in a solution of methanol, water and acetic acid (approximately 10:1:1, 3 hours ambient temperatures) and gives methyl 9.alpha.,15.alpha.-dihydroxy-15.beta.-methyl-5cis-13trans,17cis-prostatrienoate, methyl 9.alpha.,15.beta.-dihydroxy-15.alpha.-methyl-5cis,13trans,17cis-prostatrienoate, methyl 9.beta.,15.alpha.-dihydroxy-15.beta.-methyl-5cis,13trans,17cis-prostatrienoate and methyl 9.beta.,15.beta.-dihydroxy-15.alpha.-methyl-5-cis,13trans,17cis-prostatrienoate separated by dry column chromatography and further purified by partition chromatography saponification (method of Example 122) of each component in 50% aqueous methanol with potassium hydroxide gives the corresponding free acids.
Treatment of a solution of methyl 9.alpha.,15.alpha.-dihydroxy-15.beta.-methyl-5cis,13trans,17cis-prostatrienoate in methylene chloride with Collins reagent (CrO.sub.3 -pyridine in methylene chloride) gives methyl 9-oxo-15.alpha.-hydroxy-15.beta.-methyl-5cis,13trans,17cis-prostatrienoate, saponification of which (method of Example 122) gives 9-oxo-15.alpha.-hydroxy-15.beta.-methyl-5cis,13trans,17cis-prostatrienoate acid.
Similar treatment of the 15.beta.-hydroxy esters gives methyl 9-oxo-15.beta.-hydroxy-15.alpha.-methyl-5cis,13trans,17cis-prostatrienoate which gives 9-oxo-15.beta.-hydroxy-15.alpha.-methyl-5cis,13trans,17cis-prostatrienoic acid saponfication.

The residue is dry-column chromatography upon silica gel using 4:1 benzene-ethyl acetate as eluent to afford a mixture of 11-deoxy-8.beta.-methyl-prostaglandin E.sub.1 methyl ester and 11-deoxy-8.alpha.-methyl-8-iso-prostaglandin E.sub.1 methyl ester and a mixture of methyl 15-hydroxy-8.beta.-methyl-9-oxo-13-cis-prostenoate and methyl 15-hydroxy-8.alpha.-methyl-9-oxo-8-iso-13-cis-prostenoate. Further separation of the 8.beta. and 8.alpha. isomers is accomplished by a combination of partition chromatography and thin layer chromatography.
