Description

The present invention relates to novel .beta.-substituted cinnamic acid derivatives which inhibit the mitochondrial respiration of fungi, insects and spider mites, and which have antimycotic, insecticidal and acaricidal effects and, in particular, fungicidal effects on phytopathogenic fungi.
The present invention also relates to processes for the preparation of compounds of this type and to intermediates for the preparation thereof, and to processes and agents for use as fungicides, antimycotics, insecticides and acaricides, which respectively make use of and contain these .beta.-substituted cinnamic acid derivatives.
The use of amides of cinnamic acid, e.g. of the morpholide of .beta.-phenylcinnamic acid, as fungicide has been disclosed (DE 3 306 996). However, its fungicidal effect is unsatisfactory.
The present invention relates to .beta.-substituted cinnamic acid derivatives of the formula 1 ##STR3## where R.sup.1 is unsubstituted or halogen- (F, Cl, Br, I), C.sub.1 -C.sub.6 -alkoxy-, C.sub.1 -C.sub.6 -alkylthio- or C.sub.3 -C.sub.6 -cycloalkyl-substituted C.sub.1 -C.sub.8 -alkyl, C.sub.2 -C.sub.8 -alkenyl, C.sub.2 -C.sub.8 -alkynyl, C.sub.3 -C.sub.8 -cycloalkyl or C.sub.3 -C.sub.8 -cycloalkenyl, and R.sup.1 can also be chlorine or bromine when m is 0,

Alkyl for Z and R.sup.12 to R.sup.28, R.sup.38 and R.sup.39 in the compounds of the formula 1 is, as independent group or as part of a group (eg. in alkoxy, alkylthio, hetarylalkyl, aryloxyalkyl), straight-chain or branched with 1 to 10 carbon atoms, preferably with 1 to 6 and particularly preferably with 1 to 4 carbon atoms, eg. methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tertbutyl and n-decyl. Cycloalkyl has, for example, 3 to 8 C atoms, eg. cyclopropyl, cyclohexyl or cyclooctyl.

(Since alkenyl can in turn be substituted by alkenyl, Z or R.sup.12 to R.sup.28 or R.sup.38 and R.sup.39 can also be, for example, larger radicals, eg. 4,8-dimethyl-1,3,7-nonatrienyl.)
Aralkenyl is, for example, 2-(.alpha.-naphthyl)ethenyl or, particularly preferably, 2-phenylethenyl. Aryloxyalkenyl is, for example, 2-phenoxyethenyl.

Preferred groups Z, R.sup.12 to R.sup.28, R.sup.38 and R.sup.39 within this range are those whose number of carbon atoms does not exceed 28, irrespective of the type and number of any hetero atoms. Although compounds of the formula 1 in which Z, R.sup.12 to R.sup.28, R.sup.38 and R.sup.39 have larger numbers of carbons may still have biological, eg. fungicidal, activity, on occasion their effect or their practical application is prevented by excessive lipophilicity and/or insufficient solubility and/or particular difficulty in preparation.
Furthermore, compounds of the formula 1 which are particularly active and therefore preferred are those in which the total number of carbon atoms in Z, R.sup.12 to R.sup.28, R.sup.38 and R.sup.39 is more than 4, irrespective of the type and number of any hetero atoms. Compounds of the formula 1 where Z, R.sup.12 to R.sup.28, R.sup.38 and R.sup.39 have a smaller number of carbon atoms may, however, also have biological, eg. fungicidal, activity. On the other hand, such compounds of the formula 1 according to the invention are of particular interest not just because of their biological effect but much more because they can often be used particularly well as intermediates for synthesising other compounds of the formula 1 with even greater activity.
Examples of compounds of the formula 1 which are particularly preferred as intermediates are those in which Z is Cl, Br, cyano, --SH, --NH.sub.2, --CH.sub.3, --C.sub.2 H.sub.5, --CH.sub.2 Cl, --CH.sub.2 Br, CH.sub.2 OCH.sub.3, --CH.sub.2 OH, --acetyl, --CH.dbd.CH.sub.2, --C.tbd.CH, --O--CH.sub.2 --CH.dbd.CH.sub.2 and in which Z can also be CHO, OH or COOH if m is 1.
Such compounds of the formula 1 can be used to prepare, by building up the side chain Z, other compounds of the formula 1 which have even greater activity and in which, for example, the number of carbon atoms in Z is in the abovementioned preferred range of from more than 4 to 28 C atoms.
The .beta.-substituted cinnamic acid derivatives according to the invention can exist as E and Z isomers. The invention embraces both isomers, and isomers in which R.sup.1 --X.sub.m -- is trans relative to COY are preferred in principle. By the Cahn-Ingold-Prelog nomenclature (see, for example, J. March, "Advanced Organic Chemistry", 3rd edition, Wiley-Interscience, pp. 109 et seq.) these are the E isomers when m is 1 and the Z isomers when m is 0. ##STR5##
In the examples of the individual compounds (see Tables 1, 1a and 1b) for simplicity the isomers are called cis and trans with the above meanings.
The isomers can be separated by conventional processes such as crystallization or chromatography. The trans isomers are preferred for the uses according to the invention as fungicides, acaricides, insecticides or antimycotics. When the synthesis produces mixtures of isomers, separation is not absolutely necessary because in some cases the individual isomers are interconvertible when used according to the invention (for example as fungicides on land in the open), eg. due to the action of light, acids or bases, specifically also in vivo.
The present invention embraces both the individual isomers and mixtures thereof, and they are all biologically active.
The present invention comprises inter alia in particular compounds of the formula 1 where X is oxygen or sulfur and m is 0 or 1.
The present invention also comprises inter alia in particular those compounds of the formula 1 where R.sup.1 is straight-chain or branched C.sub.1 -C.sub.4 -alkyl.

Particularly preferred compounds of the formula 1 are those where Y is methoxy. These surprisingly have a particularly low toxicity for mammals.

Where --A-- contains a --C.dbd.C--, --C.dbd.N--, --N.dbd.C-- --N.dbd.N-- double bond, the preferred isomers are those where R.sup.29 is trans relative to the phenyl of the cinnamic acid.
The present invention also comprises in particular those compounds of the formula 1a where R.sup.29 is five- or six-membered aryl or hetaryl which is unsubstituted or substituted one or more times by halogen, C.sub.1 -C.sub.12 -alkyl, C.sub.1 -C.sub.12 -haloalkyl, C.sub.2 -C.sub.12 -alkenyl, C.sub.2 -C.sub.12 -alkynyl, unsubstituted or substituted aryl, unsubstituted or substituted hetaryl, unsubstituted or substituted aralkyl, C.sub.1 -C.sub.12 -alkoxy, C.sub.1 -C.sub.12 -haloalkoxy, C.sub.2 -C.sub.12 -alkenyloxy, C.sub.2 -C.sub.12 -alkynyloxy, unsubstituted or substituted aryloxy, formyl, C.sub.1 -C.sub.12 -acyl, cyano, trifluoromethyl, nitro or --CR.sup.32 .dbd.N--OR.sup.33 and/or may be fused to a benzene ring, where R.sup.32 is hydrogen or C.sub.1 -C.sub.4 -alkyl and R.sup.33 is hydrogen, C.sub.1 -C.sub.8 -alkyl, C.sub.2 -C.sub.8 -alkenyl or C.sub.2 -C.sub.8 -alkynyl.

Table 1b lists examples of compounds of the formula 1b according to the invention.
See above (page 9) for information on the identification of the isomers as trans or cis in the tables. The structural assignment was confirmed by X-ray structural analysis of the free acid (with Y.dbd.OH in place of methoxy) obtained from compound No. 1.1 in Table 1 by hydrolysis, and of compound No. 1a.310 in Table 1a. The assignment is easily made from the .sup.1 H NMR spectrum. The olefinic proton in position .alpha. to the group COY appears at a lower field in the trans isomers than in the cis isomers.
.sup.1 H NMR spectral data in the following tables relate to the olefinic proton in position .alpha. to the group COY; unless otherwise indicated, CDCl.sub.3 was used as solvent.

It is known that inhibitors of the mitochondrial respiration of fungi can be used as fungicides, e.g., antimycin (cf. U.S. Rieske in M. Erecinska, D. F. Wilson (ed.) "Inhibitors of Mitochondrial Function", Pergamon Press, Oxford, 1981, p. 110). However, there are various drawbacks to the use of antimycin, e.g., its production is difficult and elaborate, and it is insufficiently stable when used in the open.
The cinnamic acid derivatives according to the invention inhibit the mitochondrial respiration of fungi (v. Use Example 1) and may be used as fungicides.
Mitochondrial respiration is essential for metabolism. With the aid of respiration, energy is stored in the mitochondria in the form of adenosine triphosphate (ATP). The inhibition of respiration caused by mitochondrial respiration inhibitors ultimately results in the inhibition of ATP formation. As a consequence, metabolic processes dependent on ATP or energy come to a stop in fungi treated with .beta.-substituted cinnamic acid derivatives according to the invention, growth coming to a standstill or the fungi dying.
Further, the compounds according to the invention may also be used as animal or human antimycotics, as the mitochondrial respiration of animal-pathogenic and human-pathogenic fungi is inhibited. Some of the compounds are also effective on insects and spinning mites, as mitochondrial respiration is also inhibited in these organisms (v. Use Example 1).
Certain .beta.-aryl-substituted cinnamides having a fungicidal action, e.g., .beta.-phenylcinnamyl morpholide, are known from German Offenlegungsschrift 33 06 996. However, these compounds have virtually no effect on the mitochondrial respiration of fungi (v. Use Example 1) and their fungicidal action on several fungi is unsatisfactory.
By contrast, the compounds according to the invention have a broad spectrum of action both on Phycomycetes and Ascomycetes, Basidiomycetes and Deuteromycetes.
The novel compounds are suitable for use as fungicides.
The compounds I according to the invention, or fungicidal agents containing them, may be applied for instance in the form of directly sprayable solutions, powders, suspensions (including high-percentage aqueous, oily or other suspensions), dispersions, emulsions, oil dispersions, pastes, dusts, broadcasting agents, or granules by spraying, atomizing, dusting, broadcasting or watering. The forms of application depend entirely on the purpose for which the agents are being used, but they must ensure as fine a distribution of the active ingredients according to the invention as possible.
Normally, the plants are sprayed or dusted with the active ingredients or the seeds of the crop plants are treated with the active ingredients.
The formulations are produced in known manner, for example by extending the active ingredient with solvents and/or carriers, with or without the use of emulsifiers and dispersants; if water is used as solvent, it is also possible to employ other organic solvents as auxiliary solvents. Suitable auxiliaries for this purpose are solvents such as aromatics (e.g., xylene), chlorinated aromatics (e.g., chlorobenzenes), paraffins (e.g., crude oil fractions), alcohols (e.g., methanol, butanol), ketones (e.g., cyclohexanone), amines (e.g., ethanolamine, dimethylformamide), and water; carriers such as ground natural minerals (e.g., kaolins, aluminas, talc and chalk) and ground synthetic minerals (e.g., highly disperse silica and silicates); emulsifiers such as nonionic and anionic emulsifiers (e.g., polyoxyethylene fatty alcohol ethers, alkyl sulfonates and aryl sulfonates); and dispersants such as ligninsulfite waste liquors and methylcellulose.
Powders, dusts and broadcasting agents may be prepared by mixing or grinding the active ingredients with a solid carrier.
Granules, e.g., coated, impregnated or homogeneous granules, may be prepared by bonding the active ingredients to solid carriers. Examples of solid carriers are mineral earths such as silicic acids, silica gels, silicates, talc, kaolin, attapulgus clay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground plastics, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, and ureas, and vegetable products such as grain meals, bark meal, wood meal, and nutshell meal, cellulosic powders, etc.
Examples of such formulations are:
I. A solution of 90 parts by weight of compound no. 1.38 and 10 parts by weight of N-methyl-.alpha.-pyrrolidone, which is suitable for application in the form of very fine drops.
II. A mixture of 20 parts by weight of compound no. 1a.108, 80 parts by weight of xylene, 10 parts by weight of the adduct of 8 to 10 moles of ethylene oxide and 1 mole of oleic acid-N-monoethanolamide, 5 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, and 5 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By finely dispersing the mixture in water, an aqueous dispersion is obtained.
III. An aqueous dispersion of 20 parts by weight of compound no. 1a.2, 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil.
IV. An aqueous dispersion of 20 parts by weight of compound no. 1.1, 25 parts by weight of cyclohexanol, 65 parts by weight of a mineral oil fraction having a boiling point between 210.degree. and 280.degree. C., and 10 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil.
V. A hammer-milled mixture of 80 parts by weight of compound no. 1a.108, 3 parts by weight of the sodium salt of diisobutylnaphthalene-.alpha.-sulfonic acid, 10 parts by weight of the sodium salt of a lignin-sulfonic acid obtained from a sulfite waste liquor, and 7 parts by weight of powdered silica gel. By finely dispersing the mixture in water, a spray liquor is obtained.
VI. An intimate mixture of 3 parts by weight of compound no. 1a.2 and 97 parts by weight of particulate kaolin. The dust contains 3 wt % of the active ingredient.
VII. An intimate mixture of 30 parts by weight of compound no. 1.1, 92 parts by weight of powdered silica gel and 8 parts by weight of paraffin oil sprayed onto the surface of this silica gel. This formulation of the active ingredient exhibits good adherence.
VIII. A stable aqueous dispersion of 40 parts by weight of compound no. 1a.2, 10 parts of the sodium salt of a phenolsulfonic acid-urea-formaldehyde condensate, 2 parts of silica gel and 48 parts of water, which dispersion can be further diluted.
IX. A stable oily dispersion of 20 parts by weight of compound no. 1b.1, 2 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, 8 parts by weight of a fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenolsulfonic acid-urea-formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil.
In general terms, the novel compounds are extremely effective on a broad spectrum of phytopathogenic fungi, in particular those from the class consisting of the Ascomycetes and Basidiomycetes. Some of them have a systemic action and can be used as foliar and soil fungicides.
The fungicidal compounds are of particular interest for controlling a large number of fungi in various crops or their seeds, especially wheat, rye, barley, oats, rice, Indian corn, lawns, cotton, soybeans, coffee, sugar cane, fruit and ornamentals in horticulture and viticulture, and in vegetables such as cucumbers, beans and cucurbits, and the seeds of these plants.
The compounds are applied by spraying or dusting the plants with the active ingredients, or treating the seeds of the plants with the active ingredients. They may be applied before or after infection of the plants or seeds by the fungi.
The novel compounds I are particularly useful for controlling the following plant diseases:
Erysiphe graminis in cereals,
Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits,
Podosphaera leucotricha in apples,
Uncinula necator in vines,
Puccinia species in cereals,
Rhizoctonia solani in cotton,
Ustilago species in cereals and sugar cane,
Venturia inaequalis (scab) in apples,
Helminthosporium species in cereals,
Septoria nodorum in wheat,
Botrytis cinerea (gray mold) in strawberries and grapes,
Cercospora arachidicola in groundnuts,
Pseudocercosporella herpotrichoides in wheat and barley,
Pyricularia oryzae in rice,
Phytophthora infestans in potatoes and tomatoes,
Fusarium and Verticillium species in various plants,
Plasmopara viticola in grapes,
Alternaria species in fruit and vegetables.
The novel compounds may also be used for protecting materials (timber), e.g., against Paecilomyces variotii.
The fungicidal agents generally contain from 0.1 to 95, and preferably from 0.5 to 90, wt % of active ingredient. The application rates depend on the type of effect desired, and vary from 0.02 to 3 kg/ha.
When the active ingredients are used for treating seed, active ingredient amounts of from 0.001 to 50, and preferably from 0.01 to 10, g per kg of seed are generally required.
In these application forms, the agents according to the invention may also be present together with other active ingredients, for example herbicides, insecticides, growth regulators, and fungicides, and may furthermore be mixed and applied together with fertilizers. Admixture with other fungicides frequently results in a greater fungicidal action spectrum.

The active ingredients may also be successfully used in the ultra-low-volume (ULV) method, where it is possible to apply formulations containing more than 95 wt % of active ingredient, or even the active ingredient without any additives.
When the active ingredients are used for combating pests in the open, application rates are from 0.1 to 2.0, and preferably from 2.0 to 1.0, kg/ha.
Surprisingly, the novel compounds have not only a very good antimycotic in vitro action, but also a good therapeutically utilizable in vivo action, especially on dermatophytes, but also on Candida. They also have anti-bacterial effects. The active ingredients are thus a valuable enrichment of the pharmaceutical art.
The action on dermatophytes, bacteria and Protozoa can be demonstrated by methods described for instance in P. Klein, Bakteriologische Grundlagen der chemotherapeutischen Laboratoriumspraxis, Springer-Verlag, Berlin, 1957. The action on yeasts can be proved in the pseudomycelium or mycelium tests with Candida albicans (cf. DE-OS 30 20 093).
In the model of guinea pig trichophytosis (Trichophyton mentagrophytes) (cf. Heffter-Heubner: Handbuch der exp. Pharmakologie, Vol. XVI/II A) the novel compounds have a good action and prevent relapse when applied externally.
The action of the compounds when applied topically in the model of experimental Candida albicans vaginitis was also good.
The compounds also have oral activity. In the experimental models of generalised candidiasis in mice and of Candida albicans vaginitis in rats the infections were satisfactorily cleared up with low oral doses of the test substances.
The compounds are therefore particularly suitable for external as well as oral treatment of fungal infections in humans and animals. Examples of indications for humans and animals are: dermatomycoses, especially caused by dermatophytes such as species of the genera Epidermophyton, Microsporum or Trichophyton, yeasts such as species of the genus Candida, and molds such as species of the genera Aspergillus, Mucor or Absidia.
The compounds can be used alone or together with known agents, especially antibiotics.
The chemotherapeutic agents or formulations are prepared with conventional solid, semisolid or liquid carriers or diluents and the auxiliaries conventionally used in pharmaceutical technology for the required mode of administration and with a dosage suitable for use in a conventional manner, in particular by mixing (cf. H. Sucker et al., Pharmazeutische Technologie, Thieme-Verlag, Stuttgart, 1978).
Examples of suitable administration forms are uncoated or coated tablets, capsules, pills, aqueous solutions, suspensions and emulsions, where appropriate sterile injectable solutions, non-aqueous emulsions, suspensions and solutions, ointments, creams, pastes, lotions etc.
The therapeutically active compound is present in pharmaceutical formulations preferably in a concentration of from 0.01 to 90% of the total weight of the mixture.
It is possible in general to administer the agent or agents orally both in human and in veterinary medicine in amounts of from about 1.0 to about 50.0, preferably 2 to 10, mg/kg of body weight per day, preferably in the form of several individual doses to achieve the required results. However, it may be necessary to deviate from the stated dosages, specifically as a function of the type and severity of the disease, the type of formulation and of administration of the drug, and the time or interval over which administration takes place. Thus, less than the abovementioned amount of agent may suffice in some cases, whereas more than the abovementioned amount of agent must be used in other cases.

USE EXAMPLE 1
Effect of the compounds as inhibitors of mitochondrial respiration.
In order to determine the effect of the compounds according to the invention on mitochondrial respiration it is first necessary to isolate the mitochondria from the organisms being investigated. For this, in the case of the yeast Saccharomyces cerevisiae, the cells in a 30 to 40% strength suspension of the yeast in an aqueous solution of 0.6M mannitol+0.01M tris[hydroxymethyl]-aminomethane+0.002M disodium ethylenediaminetetraacetate (pH 6.8) are disrupted in a glass bead mill, and the extract is fractionated by differential centrifugation at 1000.times. g and 12000.times. g. The mitochondrial are in the pellet from the 12000.times. g centrifugation.
It is also possible similarly to isolate mitochondria from other organisms, e.g. from the phytopathogenic fungus Drechslera sorokiniana (synonym: Helminthosporium sativum), from the dermatophyte Trichophyton mentagrophytes, which is a human pathogen, and, for example, from the house fly (Musca domestica) an insect or from the spider mite Tetranychus urticae.
The effect of the compounds on the respiratory chain is determined by adding a solution of the compound to be tested in dimethyl sulfoxide to a suspension of mitochondria in an aqueous solution of 0.01M tris-[hydroxymethyl]aminomethane+0.65M sorbitol+0.01M KH.sub.2 PO.sub.4 +0.01M KCl+0.0004M disodium ethylenediaminetetraacetate+0.3% bovine serum albumin+0.0007M KCN+6.times.10.sup.-6 M ubiquinone 50+0.01M sodium succinate+0.15% cytochrome c (pH 7.5), and determining the rate of reduction of cytochrome c by photometry, measuring the increase in extinction at 546 nm. Used as control is a mixture with the equivalent amount of pure DMSO. The inhibition at the concentration of agent in each case is then calculated as follows ##EQU1## where .DELTA.E is the change in extinction, .DELTA.t is the change in time, ##EQU2## is the reaction rate for the control and ##EQU3## is the reaction rate for the sample x.
The following table shows the effects of a number of compound according to the invention as inhibitors of mitochondrial respiration in the yeast Saccharomyces cerevisiae, the phytopathogenic fungus Drechslera sorokiniana and the house fly Musca domestica. The inhibition was determined in each case at a test substance concentration of 1.8/10.sup.-5 mol/1. For comparison, the corresponding value for the morpholide of .beta.-phenylcinnamic acid (A), which is disclosed in DE 33 06 996, has been indicated.

Activity against Plasmopara viticola
Leaves of potted vines of the Muller Thurgau variety were sprayed with an aqueous liquor which contained 80% of active ingredient and 20% of emulsifier in dry matter. To assess the duration of action of the active ingredient, after the sprayed-on layer had dried the plants were placed in a greenhouse for 8 days. The leaves were then infected with a suspension of Plasmopara viticola zoospores. The vines were then placed first in a chamber saturated with water vapor at 24.degree. C. for 48 hours and then in a greenhouse at from 20.degree. to 30.degree. C. for 5 days. After this, to speed up sporangiophore discharge, the plants were again placed in the humidity chamber for 16 hours. The extent of fungus attack was then assessed on the undersides of the leaves.
The result of the tests shows that novel compounds Nos. 1a.31, 1a.61, 1a.62, 1a.63, 1a.72, 1a.110, 1a.182, 1a.238, 1a.310, 1a.312, 1a.318, 1a1a.321, 1a.323, 1a.356 and 1a.394 have, when used as aqueous dispersion containing 250 ppm active ingredient, a better fungicidal effect (10% fungal attack) than the known active ingredient A (35% fungal attack).

The test plants were then placed in a greenhouse at from 20.degree. to 22.degree. C. and from 75 to 80% relative humidity. The extent of mildew spread was assessed after 7 days.
The result of the tests shows that novel compounds Nos. 1a.2, 1a.60, 1a.61, 1a.63, 1a.72, 1a.239, 1a.245, 1a.246, 1a.248, 1a.290, 1a.292, 1a.294, 1a.304 and 1a.356 have, when used as aqueous dispersion containing 250 ppm active ingredient, a better fungicidal effect (15% fungal attack) than the known active ingredient A (45% fungal attack).

Leaves of pot-grown rice seedlings of the Bahia variety were sprayed to runoff with aqueous emulsions which contained 80% of active ingredient and 20% of emulsifier in dry matter and, 24 hours later, inoculated with an aqueous suspension of Pyricularia oryzae spores. The test plants were then placed in chambers at from 22.degree. to 24.degree. C. and from 95 to 99% relative humidity. The extent of disease was assessed after 6 days.
The result of the tests shows that novel compounds Nos. 1a.72, 1a.181, 1a.248, 1a.302, 1a.314 and 1a.356 have, when used as aqueous dispersion containing 250 ppm active ingredient, a better fungicidal effect (15% fungal attack) than the known active ingredient A (60% fungal attack).
The compounds of the formula 1 where R.sup.1, U, V, W, X.sub.m, Y and Z have the abovementioned meanings can be prepared by the synthetic routes and processes described in the following section.
The compounds of the formula 3 where U, V, W, Y and Z have the abovementioned meanings are important intermediates in this connection, and the present invention relates to them. The possible ways of preparing these intermediates of the formula 3 are indicated in Scheme 1. Their use for the synthesis of final products of the formula 1 is explained thereafter (see, for example, Schemes 2 and 3). ##STR185##
The intermediates of the formula 3 are obtained, for example, by reacting the appropriate organometallic compounds 7, which in turn can be obtained by metallation or metal/halogen exchange from the corresponding precursors 5 and 6 by conventional processes (cf. Advanced Org. Chem., 3rd. Ed., 545 et seq., 1985) with the malonic acid derivatives 8 in a conventional manner (cf., for example, Houben-Weyl, Vol. VII/2a, 595 et seq.).
The intermediates of the formula 3 can be prepared from the acetophenone derivatives 10 in a condensation with the carbonic acid derivatives 9 in the presence of a base such as sodium hydride in a conventional manner (cf., for example, Org. Synth. 47 (1967) 20).
The .beta.-keto acid derivatives 3 are obtained from the benzoic acid derivatives 11 and 12 by reaction with an acetic acid derivative 13 in the presence of a base such as sodium hydride, sodium methanolate or potassium tert-butanolate in a conventional manner (cf., for example, Org. Synth. 23 (1943) 35).
Oxidation of the benzyl alcohols 14 in a conventional manner (cf. Organikum 16th Ed., page 358, 1986) likewise provides the intermediates 3. The benzyl alcohols 14 themselves can be prepared from the corresponding aldehydes 15 by processes known from the literature, eg. by a Reformatsky synthesis (cf., for example, J.Org.Chem., 35 (1970) 3966).
The intermediates 3 can also be prepared from the benzene derivatives of the formula 5 by Friedel-Crafts acylation, in the presence or absence of a catalyst such as AlCl.sub.3, FeCl.sub.3, ZnCl.sub.2, in a conventional manner (cf., for example, Organikum 16th Ed., pp. 323 et seq., 1986).
The acetophenones 10, benzoic acid derivatives 11 and 12 and benzaldehydes 15 which can be employed as precursors are either known or preparable by a conventional method, e.g. from the metallated intermediates of the formula 7 by reaction of an electrophile, eg. with an acetic acid derivative (.fwdarw.10), a carbonic acid derivative (.fwdarw.12) or a formic acid derivative (.fwdarw.15).
The compounds of the formula 1 where R.sup.1, U, V, W, Y and Z have the abovementioned meanings and where X is oxygen and m is 1 can be prepared, for example, as shown in Scheme 2. ##STR186##
Reaction of the .beta.-keto acid derivatives 3, in particular the .beta.-keto esters, in a conventional manner with an alkylating agent R.sup.1 Nuc, e.g. with a dialkyl sulfate such as dimethyl sulfate or with an alkyl halide such as methyl chloride or butyl chloride, in a solvent or diluent such as dimethyl sulfoxide or hexamethylphosphoric triamide, in the presence or absence of a base such as sodium hydride or potassium tert-butylate, results in compounds of the formula 1 where X.sub.m is oxygen (cf., for example, Synthesis (1970) 1).
An alternative possibility is to react .beta.-keto acid derivatives of the formula 3 in a conventional manner with an orthoformic ester 18, in the presence or absence of an acid such as hydrochloric acid, sulfuric acid or p-toluenesulfonic acid. The resulting ketals 19 can be either isolated and then converted into the products 1 by heating, or else converted directly without isolation into the products 1 (cf. Houben-Weyl, Vol. 6/3, page 112, 1965).
The novel compounds of the formula 1 can be prepared from the acetylene derivatives 20 by addition of an alcohol R.sup.1 OH, in the presence or absence of a catalyst such as HCl or KOH (cf., for example, Houben-Weyl, Vol. 6/3, page 114, 1965).
The acetylene derivatives 20 themselves can be obtained by conventional processes, for example, from the .beta.-keto acid derivatives 3, eg. by reaction with triphenylphosphine oxide (cf., for example, Synthesis (1989) 217).
In addition, the novel compounds of the formula 1 can be prepared from the vinyl halides 21 by nucleophilic substitution with an alcohol R.sup.1 OH in the presence or absence of a base such as sodium hydride (cf., for example, J. Org. Chem. 50 (1985) 4664).
The vinyl halides 21 themselves can be obtained, for example, by halogenation of the .beta.-keto acid derivatives 3 in a conventional manner (cf., for example, Org. Synth. 6 (1926) 505).
Scheme 3 explains the synthesis of compounds of the formula 1 where R.sup.1, U, V, W, Y and Z have the abovementioned meanings, and where X.sub.m is sulfur (corresponds to formula 22 in Scheme 3). ##STR187##
The novel compounds of the formula 22 can be prepared from the acetylene derivatives 20 by addition of a thiol R.sup.1 SH in the presence or absence of a base such as KOH or pyridine, or of an acid such as HCl (cf., for example, E. Larsson, J. Prakt. Chem. 325 (1983) 328; Synthesis 12 (1986) 1070; Houben-Weyl Vol. 9., page 133 1955).
Compounds of the formula 22 can also be prepared by reacting .beta.-keto acid derivatives, especially .beta.-keto esters 3, in a conventional manner in the presence or absence of an acid such as hydrochloric acid, sulfuric acid or p-toluenesulfonic acid, or of a Lewis acid such as ZnCl.sub.2 or BF.sub.3, with thiols R.sup.1 SH. The resulting thioketals 23 can be converted either directly or, after isolation, by heating into the products 22 (cf., for example, Angew. Chem. 77 (1965) 1140; J. Org. Chem. 40 (1975) 812).
Compounds of the formula 22 can be prepared from compounds of the formula 21 or 21a by reaction with thiols R.sup.1 SH, in the presence or absence of a base, in a conventional manner. Compounds of the formula 21a can be prepared by reacting compounds of the formula 3 with sulfonyl chlorides R.sup.1 SO.sub.2 Cl such as methanesulfonyl chloride (R'=methyl) or toluenesulfonyl chloride (R'=p-methylphenyl), with or without the addition of bases (e.g. triethylamine or sodium hydride).
Compounds of the formula 22 can also be prepared by reacting compounds of the formula 1 where X is oxygen and m is 1 with thiols R.sup.1 SH under acidic or alkaline conditions.
The enamines of the formulae 24 and 25 (corresponding to formula 1 with X.sub.m =NR.sup.2 and NOR.sup.3 respectively) where R.sup.1, R.sup.2, R.sup.3, U, V, W, Y and Z have the abovementioned meanings can be prepared, for example, as shown in Scheme 4. ##STR188##
The novel compounds of the formula 24 can be prepared from compounds of the formula 20 in a conventional manner by addition of amines of the formula R.sup.1 R.sup.2 NH (cf., for example, Houben-Weyl, Vol. 11/1, pages 299 et seq. 1957). The compounds of the formula 25 can be prepared similarly by addition of alkoxyamines R.sup.1 R.sup.3 ONH onto compounds of the formula 20.
Enamines of the formula 24 can furthermore be prepared by reacting .beta.-keto acid derivatives, especially .beta.-keto esters 3 with primary or secondary amines R.sup.1 R.sup.2 NH, where appropriate under acidic or basic conditions in a conventional manner (cf., for example, Houben-Weyl, Vol. 11/1, page 172, 1957). For example .beta.-keto esters 3 can firstly be converted with a base such as sodium hydride or sodium hydroxide into the enolates which react with the hydrochlorides of primary or secondary amines to give compounds of the formula 24 with liberation of sodium chloride (cf., for example, Ann. Chim. [10] 18 (1932) 103; J. Am. Chem. Soc. 70 (1948) 3350). Compounds of the formula 25 are prepared from .beta.-keto acid derivatives 3 similarly by reaction with alkoxyamines R.sup.3 ONHR.sup.1.
It is furthermore possible to prepare enamines 24 by reacting compounds of the formula 1 where X is oxygen and m is 1 with primary or secondary amines R.sup.1 R.sup.2 NH, where appropriate under acidic or basic conditions, in a conventional manner (cf., for example, Houben-Weyl, Vol. 11/1, page 198 (1957); J. Heterocycl. Chem. 21 (1984) 1753; Indian J. Chem. 27 (1988) 1044).
Scheme 5 illustrates the synthesis of compounds of the formula 1 where R.sup.1, U, V, W, Y and Z have the abovementioned meanings, and m is 0 (corresponding to formula 26 in Scheme 5). ##STR189##
The .beta.-alkylcinnamic acid derivatives 26 are obtained from the aryl ketones 27 by, for example, reaction in a conventional manner (cf., for example, Tetrahedron 46 (1990) 5859) with a Wittig reagent or Wittig-Horner reagent of the formula 28 or 29 in an inert organic solvent in the presence of a base such as sodium hydride or potassium t-butylate. Hal in the formula 28 is a halogen atom such as chlorine or bromine. R" in the formula 29 is alkoxy such as methoxy or ethoxy.
An alternative possibility for the preparation of compounds of the formula 26 is to react 27 in a conventional manner (cf., for example, Bull. Soc. Chim. Belg. 79 (1970) 61-74) with .alpha.-haloacetic acid derivatives of the formula 30 and zinc in a Reformatsky reaction, followed by dehydration. Hal in formula 30 is chlorine or bromine.
The aryl ketones 27 are either known or obtainable by known methods, for example from compounds of the formula 7 by reaction with carboxylic acid derivatives R.sup.1 COY' where Y' is halogen, OR or NR.sub.2, or from compounds of the formula 11 or 12 by reaction with organometallic compounds R.sup.1 M.
Compounds of the formula 1, where COY represents the various suitable ester, thiol ester and amide groups can easily be prepared by a number of standard processes by conversion of COY (see, for example, Houben-Weyl, Methoden der Organischen Chemie, Volume E5 and preparation examples 9-11). Thus, for example, the esters of the formula 1 where Y is OR.sup.4 can easily be converted into the corresponding carboxylic acids by hydrolysis by conventional processes (see, for example, Houben-Weyl, Volume E5, pages 223-254, specifically 231-237). The latter can subsequently be converted into activated derivatives such as the imidazolides with Y.dbd.1-imidazolyl or the chlorides with Y.dbd.Cl (see, for example, Houben-Weyl, Volume VIII, pages 463 et seq.). In turn, reaction of the latter with alcohols or oximes gives the corresponding esters of the formula 1 with Y.dbd.OR.sup.4 or the oxime esters with Y.dbd.O--N.dbd.CR.sup.5 R.sup.6 (see, for example, Houben-Weyl, Volume VIII, pages 543 et seq.), or with thiols gives the corresponding thiol esters of the formula 1 with Y.dbd.SR.sup.11 (see, for example, Houben-Weyl, Volume IX, pages 753-755), or with amines gives the corresponding amides of the formula 1 with Y.dbd.NR.sup.7 R.sup.8 or Y.dbd.N(OR.sup.9)R.sup.10 (see, for example, Houben-Weyl, Volume VIII, pages 655 et seq.).
The novel compounds of the formula 1b where V, W, X.sub.m, Y and R.sup.1 have the meanings stated in claim 1, and Z and U in adjacent positions on the phenyl ring together form an unsubstituted or substituted five- or six-membered aromatic or heteroaromatic ring, are prepared by the processes described above from the corresponding benzo-fused intermediates, eg. similar to the synthetic routes indicated in Schemes 1 to 5. The preparation of the fused intermediates is described hereinafter (cf. Schemes 6 to 8).
For example, suitable precursors are 1,7-disubstituted naphthalene derivatives of the formula 10a which are known or can be prepared in a conventional manner. For example, compounds of the formula 10a are obtained from 2-substituted naphthalenes by Friedel-Crafts acylation, in the presence or absence of a catalyst such as AlCl.sub.3, FeCl.sub.3, ZnCl.sub.2, similar to known methods (cf., for example, J. Chem. Soc. C (1966) 518). ##STR190## V, W, Hal, R.sup.29, R.sup.35 and R.sup.36 as defined above.
Furthermore, compounds of the formula 6a where R.sup.29 has the abovementioned meanings are obtained from (2-halophenyl)acetic acid derivatives, for example the corresponding chlorides, by reaction with ethylene in the presence of a Lewis acid, for example AlCl.sub.3, to give the ketones 72. Reaction of the ketones with organometallic compounds R.sup.29 M, for example with organolithium compounds or Grignard compounds, provides the alcohols 73 which are aromatised with triphenylmethanol under acidic conditions to give the naphthalene derivatives 6a which are required as intermediates (cf., for example, EP 393 941). The latter can be converted by the routes explained in Scheme 1 into the final products of the formula 1 or 1b.
The 2-substituted 8-quinolinecarboxylic acid derivatives of the formula 12b required as intermediates can be obtained from aldehydes and o-toluidines, when R.sup.36 .dbd.R.sup.29, as shown in the following Scheme 7: ##STR191##
Aldehydes undergo a Doebner reaction with o-toluidines to give 2-substituted 8-methylquinoline-4-carboxylic acids which are converted by copper-catalyzed decarboxylation into the corresponding methylquinolines. Oxidation of the methyl group by conventional methods gives the required 8-quinolinecarboxylic acids 12b (cf., for example, J. Am. Chem. Soc. 68 (1946) 1589).
Furthermore, when R.sup.36 .dbd.R.sup.29, 8-quinolinecarboxylic acids of the formula 12b are obtained from Schiff's bases of anthranilic acid derivatives by reaction with vinyl ethers in the presence of an acid catalyst, for example H.sub.2 SO.sub.4 or BF.sub.3, and subsequent oxidative aromatisation of the 4-alkoxy-1,2,3,4-tetrahydroquinoline-8-carboxylic acid, for example with KMnO.sub.4 (cf., for example, Izv. AN SSSR, Ser. kim. (1966) 120 (Engl.)).
In the case where R.sup.36 is OR.sup.12, SR.sup.13 or NR.sup.37 R.sup.38, the compounds 12b can be obtained from the 2-haloquinolines by reaction with an alcohol (R.sup.12 OH), a mercaptan (R.sup.13 SH) or an amine (R.sup.37 R.sup.38 NH), in the presence or absence of a base. The 2-haloquinolines are obtained by conventional processes (cf., for example, Houben-Weyl, Vol. V/3, 920) from the 2-quinolones (cf., for example, Chem. Pharm. Bull. 34 (1986) 682).
The carboxylic acids of the formula 12b are then converted into the esters or halides, which are converted like the compounds of the formula 11 or 12 by the routes shown in Schemes 1 and 2 into the final products of the formula 1 or 1b.
5-Quinolinecarboxylic acid derivatives of the formula 12c are obtained from 3-aminobenzoic acids and .beta.-alkoxyacryloyl halides as shown in Scheme 8: ##STR192##
The 2-quinolones are converted into the quinolines by conventional methods (cf., for example, J. Heterocyclic Chem. 24 (1987) 351).
Further quinoline intermediates can be prepared by processes similar to those described in Chem. Heterocyclic Comp. Vol. 32, Chap. 2.
Quinazolines can be obtained from o-aminobenzaldehydes by Bischler condensation with ammonia (cf., for example, J. Chem. Soc. (1965) 5360).
Cinnolines can be obtained from 2-aminoacetophenones by diazotization and cyclization to 4-hydroxycinnolines in a Borsche synthesis (cf., for example, Liebigs Ann. Chem. 546 (1941) 293) and subsequent reduction (cf., for example, J. Chem. Soc. (1959) 2858).
Quinoxalines can be obtained from o-phenylenediamines by reaction with .alpha.-bromo ketones and oxidation to the aromatic system (cf., for example, J. Chem. Eng. Data 18 (1973) 102).
1,2,4-Benzotriazines are prepared from o-nitrophenylhydrazides of carboxylic acids by known processes (cf., for example, Chem. Ber. 22 (1889) 2801).
3,5-disubstituted isoquinolines are known or can be prepared by known processes (cf., for example, J. Org. Chem. 23 (1958) 435).
2,4- and 2,7-disubstituted benzoxazoles are obtained by conventional processes from o-aminophenols by reaction with a carboxylic acid derivative, eg. a carbonyl chloride (cf., for example, J. Med. Chem. 20 (1977) 169). The o-aminophenols which can be employed as precursors are known or can be prepared by known methods (cf., for example, Biochem. Prep. 6 (1958) 20).
2,4-disubstituted indole derivatives can be prepared from 2-haloanilines, for example 2-bromoanilines, and enamines in the presence of a transition metal catalyst such as a Pd compound (cf., for example, J. Heterocycl. Chem. 24 (1987) 1555).
2,4-disubstituted benzofuran derivatives are obtained by conventional processes from 2-vinylfurans and acetylene derivatives, for example methyl propiolate, by cycloaddition and subsequent oxidation (cf., for example, Aust. J. Chem. 26 (1973) 1059).
2,4- and 2,7-disubstituted benzimidazoles are known or can be prepared in a conventional manner from o-phenylenediamines and carboxylic acids or derivatives thereof in the presence of a condensing agent, for example phosphonium anhydride (cf., for example, J. Org. Chem. 54 (1989) 1144). 2,4-disubstituted benzothiazoles are known or can be prepared by known processes from 2-halothioanilides (cf., for example, Synthesis (1976) 730).
The synthesis of the various side chains Z is explained in detail in Schemes 9 to 21 which follow.
For example, compounds of the formula 33 can be prepared by the routes indicated in Scheme 9. ##STR193## R.sup.1, R.sup.4, R.sup.12, R.sup.17, R.sup.30, R.sup.31, U, V, W, X, Y, m as defined above.
The benzyl halides of the formula 32 where R.sup.31 is preferably hydrogen can be prepared by conventional methods by reacting the compounds 31 where R.sup.31 is likewise preferably hydrogen with a halogenating agent such as chlorine, bromine, iodine, N-bromosuccinimide or N-chlorosuccinimide in an inert solvent such as tetra-chloromethane, methylene chloride or cyclohexane, with our without exposure to a light source (e.g. Hg vapor lamp, 300 W) or addition of free radical initiators such as dibenzoyl peroxide or azoisobutyronitrile [see Angew. Chem. 71 (1959) 349].
Compounds 32 with Hal=iodide can also be prepared by methods known from the literature from the chlorides or bromides by reaction with, for example, sodium iodide in acetone [see J. Chem. Soc., Perkin Trans. I (1976) 416].
The benzyl halides 32 where R.sup.31 is preferably hydrogen can be reacted by standard processes with nucleophiles, preferably N, O or S nucleophiles such as carboxylic acids, phenols, alcohols, mercaptans, amines and oximes, to give the compounds 33 according to the invention where R.sup.31 is again preferably hydrogen, for example by reacting the compounds of the formula 32 with the abovementioned nucleophiles themselves or with the alkali metal, alkaline earth metal, silver or ammonium salts derived therefrom in a solvent such as acetone, acetonitrile, toluene, DMF or THF, with or without the addition of a catalyst, eg. 0.01 to 10% by weight potassium iodide [see Organikum, 17th Ed., pages 172 et seq., VEB Berlin (1988); Org. Synth. Coll. Vol. 5, pages 1031 et seq., J. Wiley & Sons (1973)].
The compounds of the formulae 35, 38, 39 and 40 can be prepared as described in Scheme 10, for example. ##STR194## Hal=Cl, Br, I R.sup.100 =Phenyl
R.sup.101 =C.sub.1 -C.sub.8 -alkyl
G, R.sup.29, R.sup.30, R.sup.31, U, V and W as defined above.
The benzyl halides of the formula 32 where R.sup.31 is preferably hydrogen can be reacted with oxidizing agents such as N-methylmorpholine N-oxide monohydrate or dimethyl sulfoxide in a conventional manner to give the oxo compounds 35 where R.sup.31 is again preferably hydrogen [see J. Org. Chem. 24 (1959) 1792].
To prepare the olefins 38, the oxo compounds 35 can be reacted, for example, with a phosphonic ester of the formula 36 or a phosphonium salt of the formula 37. The reaction is carried out in a conventional manner [see J. Am. Chem. Soc. 83 (1961) 1733; Angew. Chem. 71 (1959) 260].
The starting materials are normally employed in the stoichiometric ratio. An excess of up to 10% (by weight) of one of the reactants above the stoichiometric amount is possible. The reaction is carried out in an inert solvent or diluent (eg. hexane, toluene, methylene chloride, dimethyl sulfoxide, particularly preferably tetrahydrofuran, dimethylformamide or diethyl ether; it is also possible to use mixtures of the said solvents) in the presence of an equivalent amount of a base (e.g. sodium hydride, sodium amide, potassium tert-butylate, sodium methylate, butyllithium, lithium diisopropylamide, potassium hydroxide).
The reactions normally take place in the range from -70.degree. C. to +80.degree. C., preferably -70.degree. C. to +60.degree. C.
The invention relates to both the E and Z isomers, but especially to the E isomers.
The phosphonates 36 and phosphonium salts 37 can easily be obtained from the halides R.sup.30 R.sup.29 -CH-Hal (Hal=Cl, Br, I) [see Houben-Weyl, 4th Ed., Vol. XII/1, pages 79 et seq. and 433 et seq. (1963)].
As an alternative, the olefins 38 can also be obtained by reaction of the carbonyl compounds 41 with the phosphonium salts 39 or the phosphonic esters 40 [see J. Am. Chem. Soc. 83 (1961) 1733); Angew. Chem. 71 (1959) 260].
The phosphonium salts 39 and phosphonic esters 40 are obtained, for example, by reacting the halides 32 with a phosphine of the formula P(R.sup.100).sub.3 or a phosphite of the formula P(OR.sup.101).sub.3. The reaction is carried out in a conventional manner [see Houben-Weyl, 4th Ed. Vol. XII/1, pages 79 et seq. and 433 et seq. (1963)].
The phosphonates of the formula 40 with R.sup.31 .noteq.hydrogen can also be prepared, for example, by reacting the phosphonates 40 where R.sup.31 =H with alkyl halides R.sup.31 -Hal (Hal=Cl, Br, I) using a base [see J. Am. Chem. Soc. 83 (1961) 1733].
The hydrogenation of the styrene derivatives 38 with diimine or else with H.sub.2 in the presence of suitable hydrogenation catalysts such as Pd or Pt in suitable organic solvents such as tetrahydrofuran, methanol or acetic acid in a conventional manner gives the alkylated aromatic compounds 42 [see Organikum, 17th Ed. pages 288 et seq., VEB Berlin (1988)] (Scheme 11).
The compounds of the formulae 43 to 47 can be prepared, for example, as described in Scheme 12. ##STR195## G, R.sup.29, R.sup.30, R.sup.31, U, V, W as defined above ##STR196## G, R.sup.17, R.sup.18, R.sup.29, R.sup.31, U, V, W as defined above
The reaction of the oxo compounds 35 with primary amines R.sup.29 --NH.sub.2 to give the Schiff's bases 43 and with O-substituted hydroxylamines R.sup.29 O--NH.sub.2 to give the oxime ethers 44 can be carried out in a conventional manner in an inert solvent or diluent such as methanol, ethanol, toluene or in a two-phase system such as toluene/water. It is possible to carry out the reaction with the addition of a suitable base such as triethylamine, sodium carbonate, potassium carbonate, potassium hydroxide or pyridine [see Houben-Weyl, 4th Ed., Vol. XI/2, pages 73 et seq. (1958); Houben-Weyl, 4th Ed., Vol. X/4, pages 55 et seq. (1968)]. The invention relates to both the E and Z isomers, especially to the E isomers.
The benzoic acids 45 can be prepared, for example, by oxidation of the aldehydes 35 (R.sup.31 =H) by known processes [see J. March, Advanced Organic Chemistry, 3rd Ed., pages 629 et seq., Wiley-Interscience Publication (1985)].
Standard methods of organic chemistry can be used to obtain further carboxylic acid derivatives therefrom, such as the esters 46 and amides 47 [see Organikum, 17th Ed., pages 400 et seq., VEB Berlin (1988)].
Schemes 13 to 15 illustrate the synthesis of compounds of the formula 1 where the side chain Z is OH, SH or NH.sub.2 (cf. formulae 49, 50 and 51). These compounds are of particular interest as intermediates for synthesizing other compounds of formula 1 (eg. as shown in Scheme 17) and the present invention therefore also relates to them. ##STR197## R.sup.1, U, V, W, X.sub.m, Y as defined above.
The ortho-substituted phenols 49 can be obtained as described in Scheme 13 in a conventional manner from the benzyl ethers 48 by catalytic hydrogenation (cf., for example, Prot. Groups in Org.

.delta.=2.51 (s, 3H); 3.81 (s, 3H); 5.49 (s, 1H); 7.29-8.00 (m, 5H); 8.10 (s, 1H) ppm
b) 30 g (0.22 mol) of potassium carbonate are added to a stirred mixture of 48 g (0.2 mol) of methyl 7-methyl-1-naphthoylacetate and 250 ml of N,N'-dimethylpropyleneurea, and the mixture is stirred at 40.degree. C. for 2 h. It is subsequently cooled to 0.degree.-5.degree. C., and a mixture of 27.7 g (0.22 mol) of dimethyl sulfate and 50 ml of N,N'-dimethylpropyleneurea is added dropwise. The mixture is then stirred at 40.degree. C. for a further 2 h and subsequently water and methyl tert-butyl ether are added. The aqueous phase is extracted once more with methyl tert-butyl ether, and the combined organic phases are dried over Na.sub.2 SO.sub.4 and concentrated. The residue is taken up in 200 ml of N,N'-dimethylpropyleneurea, and 2.2 g (0.1 mol) of NaH are added. The mixture is stirred at room temperature for 15 h and then 50 ml of methanol are added, and the mixture is diluted with water and extracted with methyl tert-butyl ether. The organic phase is washed with water, dried over Na.sub.2 SO.sub.4 and concentrated. The residue is purified by column chromatography on silica gel (first cyclohexane and then toluene). This results in 40.4 g (80%) of methyl (E)-3-methoxy-3-(7-methyl-1-naphthyl)acrylate as brown oil.

EXAMPLE 25
Preparation of methyl (E)-3-methoxy-3-(7-phenoxymethyl-1-naphthyl)acrylate (compound No. 1b.20 in Table 1b)
a) 6.2 g (0.024 mol) of methyl (E)-3-methoxy-3-(7-methyl-1-naphthyl)acrylate and 7.1 g (0.025 mol) of 1,3-dibromo-5,5-dimethylhydantoin in 100 ml of dry tetrachloromethane are refluxed while irradiating with a halogen lamp for 75 min. The mixture is subsequently filtered with suction, and the filtrate is filtered once more through a layer of silica gel. The solvent is removed by distillation, and the residue is recrystallized from methyl tert-butyl ether. This results in 6. g (67%) of methyl (Z)-2-bromo-3-methoxy-3-(7-bromomethyl-1-naphthyl)acrylate as colorless crystals of melting point 116.degree.-119.degree. C.
.sup.1 H-NMR (CDCl.sub.3): .delta.=3.40 (s, 3H); 3.41 (s, 3H); 4.63 (s, 2H); 7.40 (d, 1H); 7.50-7.61 (m, 2H); 775 (s, 1H); 7.88-7.99 (n, 2H) ppm
b) A solution of 0.7 g (5.5 mmol) of potassium phenolate in 25 ml of dimethylformamide (DMF) is added dropwise to a solution of 2.1 g (5 mmol) of methyl (Z)-2-bromo-3-methoxy-3-(7-bromomethyl-1-naphthyl)acrylate in 30 ml of DMF at room temperature, and the mixture is stirred at room temperature for 4 hours. It is then evaporated to dryness under reduced pressure, the residue is dissolved in ethyl acetate, and the organic phase is extracted twice with water, dried and concentrated. This results in 1.85 g (87%) of methyl (Z)-2-bromo-3-methoxy-3-(7-phenoxymethyl-1-naphthyl)acrylate as brownish oil.
.sup.1 H-NMR (CDCl.sub.3): .delta.=3.39 (s, 6H); 5.21 (s, 2H); 6.91-7.32 (m, 5H); 7.39 (d, 1H); 7.52 (t, 1H); 7.63 (d, 1H); 7.80 (s, 1H); 7.89-8.00 (m, 2H) ppm
c) 1.64 g (3.8 mmol) of methyl (Z)-2-bromo-3-methoxy-3-(7-phenoxymethyl-1-naphthyl)acrylate are dissolved in 30 ml of toluene and, after addition of 2.2 g (7.6 mmol) of tributyltin hydride and a few mg of .alpha.,.alpha.'-azoisobutyronitrile, the mixture is refluxed for 15 hours. It is then concentrated, and the residue is purified by column chromatography on silica gel (first cyclohexane and then toluene). The tin compounds are eluted first, and the following fraction contains 0.89 g (66%) of methyl (E)-3-methoxy-3-(7-phenoxymethyl-1-naphthyl)acrylate.
.sup.1 H-NMR (CDCl.sub.3): .delta.=3.43 (s, 3H); 3.82 (s, 3H); 5.19 (s, 2H); 5.56 (s, 1H); 6.90-7.56 (m, 8H); 7.78 (s, 1H); 7.84-7.91 (m, 2H) ppm
0.14 g (10%) of the isomeric methyl (Z)-3-methoxy-3-(7-phenoxymethyl-1-naphthyl)acrylate is obtained as second product.
.sup.1 H-NMR (CDCl.sub.3): .delta.=3.50 (s, 3H); 3.76 (s, 3H); 5.22 (s, 2H); 5.24 (s, 1H); 6.92-7.97 (m, 10H); 8.08 (s, 1H) ppm
