Novel compounds and a novel process for their preparation

BACKGROUND OF THE INVENTION

[0002] The hydronaphthalene structure can be found in many natural products and pharmaceutical agents. These include homochelidonine (structure 1 below; Slavik, J.; et al., Collect. Czech. Chem. Commun. 30:3697 (1965); Spath, E., et al., Ber., 64:1123 (1931); Bersch, H. W., Arch. Pharm. (Weinheim, Ger.), 2914:91 (1958)) an alkaloid isolated from Chelidonium plants, dihydrexidine (structure 2 below; Snyder, S. E., J. Med. Chem., 38:2395 (1995)) which shows antiparkinsonian character, etoposide (structure 3 below; Kamal, A., et al., Tetrahedron Lett. 37:3359 (1996)) which is used in the treatment of various cancers, and SF-2315B (structure 4 below; Kim, K., et al., J. Org. Chem. 60:6866 (1995)) which is a viral reverse transcriptase inhibitor. In addition, CNS agents, immunoregulatory agents and antibiotics contain variations on this framework (Perrone, R., et al., J. Med. Chem. 38:942 (1995)).

[0003] Given the large number of pharmaceutically useful compounds which contain this core skeleton, new methodology which produces functionalized hydronaphthalene skeletons (structure 1) would clearly be of value.

[0004] Previous work on oxabicyclic ring opening reactions led to a catalytic enantioselective route to dihydronaphthol (Lautens, M., et al., Tetrahedron 54:1107 (1998)) which was a key step in the total synthesis of sertraline (Lautens, M., et al, J. Org. Chem. 63:5276 (1997)). However, little is known about the ring opening of oxabenzonorbornadiene or similar compounds with the incorporation of nucleophiles during the ring opening step. Duan and Chen developed a method of introducing aryl groups by using catalytic amounts of palladium (Duan, J.-P., et al., Tetrahedron Lett., 34:4019 (1993); Duan, J.-P., et al., Organometallics 14:1608 (1995)). Moinet et al., later developed an enantioselective version of this reaction but the yields were low (Tetrahedron Lett., 36:2051 (1995)).

[0005] Catalytic organometallic processes that form carbon-heteroatom bonds are far fewer in number than those which form carbon-carbon bonds. The Wacker Process (Henry, P. M., Paladium Catalysed Oxidation of Hydrocarbons, vol. 2, Reidel, Boston, (1980)), oxidative carbonylations of amines and alcohols (Applied Homogeneous Catalysis with Organometallic Compounds: A Comprehensive Handbook in Two Volumes (eds.: B. Cornils, W. A. Herrmann), VCH, New York, (1984)) and the formation of arylamines and aryl ethers (Hartwig, J. F., Agnew. Chem. Int. Ed. 37:2046 (1998); Widenhoefer, R. A., et al., J. Am. Chem. Soc. 119:6787 (1997)) are a few that have been described to date.

Among the diseases that may be treated are Parkinson's disease, cancer and AIDS.

DETAILED DESCRIPTION OF THE INVENTION

[0135] The present invention is based upon the discovery of a new process for the formation of enantiomerically enriched compounds containing the hydronaphthalene ring structure. The process involves reacting an aza- or oxabenzonorbornadiene compound with a nucleophile in the presence of a rhodium catalyst and a phosphine ligand. Detailed procedures for the formation of precursor compounds and their use in reactions are set forth in the Examples section below. Preferred nucleophiles are alcohols, phenols, amines, and stabilized carbanions such as malonates and malonate equivalents. In cases where simple aliphatic amines are used, reactions should be performed in the presence of a tertiary amine hydrochloride. This is not necessary for other types of amines. When carboxylic acids are used, reactions should be carried out in the presence of a tertiary amine, e.g., triethylamine. Alternatively, the sodium or potassium salt of the carboxylic acid may be reacted in the presence of the hyrochloride of a tertiary amine, e.g. in the presence of triethylamine hydrochloride. It has been found that carboxylate ring-opened products can be made to undergo a subsequent transformation to produce 1,4-disubstituted dihyronaphthalenes. This is accomplished by an SN2′ addition of nucleophiles under catalytic or non-catalytic conditions to the allyl acetate functionality. For an example of the conversion of (1R*,2R*)-Malonic acid (1-tert-butyldimethylsiloxy-1,2-dihydro-naphthalen-2-yl) ester ethyl ester to (1S*,2S*)-(4-Tert-butyldimethylsiloxy-1,4-dihydro-naphthalen-2-yl) acetic acid ethyl ester see the Examples section below.

[0136] The preferred catalyst is [Rh(COD)Cl]2 and, depending upon the particular product desired, preferred ligands are DPPF or a chiral analogue of DPPF, (R)-(S)-BPPFA; (R)-(S)-PPF-PtBu2 and (S)-(R)-PPF-PtBu2. The ligands may be prepared by any process described in the literature (see, e.g., Togni et al., J. Am. Chem. Soc. 116:4062 (1994)). Reactions may be carried out using trifluoroethanol (TFE) or tetrahydrofuran (THF) as solvents under an inert atmosphere, preferably of nitrogen. The reaction temperature should typically be at least 60° C. and preferably about 80° C.

[0137] The compounds formed may be incorporated into a pharmaceutical composition and used in the treatment of a variety of diseases and conditions. Specifically, the compounds may be used in the treatment of Parkinson's disease, cancers, and AIDS. The total daily dosage of compound administered to a patient should be at least the amount required to reduce or eliminate one or more symptoms associated with the condition being treated. For example, in the treatment of Parkinson's disease, sufficient agent should be administered to reduce the severity or frequency of tremors or other movement disorders associated with the disease. In treating cancers, agents should typically be given at a dosage sufficient to reduce tumor size or at a dosage sufficient to reduce the total number of cancerous cells in a patient. The actual dose selected for an individual patient will be determined by the attending physician based upon clinical conditions and using methods well known in the art. Agents may be provided in either a single or multiple dosage regimen, e.g., a patient may be administered compounds twice a day.

[0138] Any route of administration and dosage form is compatible with the present invention, and therapeutic agents may be administered as either the sole active ingredient or in combination with other therapeutically active drugs. Routes of delivery compatible with the invention include parenteral, peroral, internal, pulmonary, rectal, nasal, vaginal, lingual, transdermal, intravenous, intraarterial, intramuscular, intraperitoneal, intracutaneous, and subcutaneous routes. Specific dosage forms that may be used include tablets, pills, capsules, powders, aerosols, suppositories, skin patches, parenterals, and oral liquids, including oil aqueous suspensions, solutions, and emulsions. Sustained release dosage forms may also be used. All dosage forms may be prepared using methods that are standard in the art (see, e.g., Remington's Pharmaceutical Sciences, 16th ed., A. Oslo, editor, Easton Pa. (1980)).

[0139] Therapeutic agents may be used in conjunction with any of the vehicles and excipients nly employed in pharmaceutical preparations, e.g., talc, gum arabic, lactose, starch, magnesium stearate, cocoa butter, aqueous or non-aqueous solvents, oils, paraffin derivatives, glycols, etc. Coloring and flavoring agents may also be added to preparations designed for oral administration. Solutions can be prepared using water or physiologically compatible organic solvents such as ethanol, 1,2-propylene glycol, polyglycols, dimethyl sulfoxide, fatty alcohols, triglycerides, partial esthers of glycerine, and the like. Parenteral compositions containing compounds may be prepared using conventional techniques and include sterile isotonic saline, water, 1,3-butane diol, ethanol, 1,2-propylene glycol, polyglycols mixed with water, Ringer's solution, etc.

[0140] If desired, a patient may be initially given a relatively low dose of therapeutic agent in order to determine whether any adverse side effects are experienced. This may be particularly important in cases where a patient is taking other medications or has clinical characteristics that suggest that they may not be able to tolerate high drug dosages. If adverse side effects are not experienced by a patient, dosage may be gradually increased until a satisfactory alleviation of symptoms is achieved. For example, the dosage given to a patient with AIDS may be increased until blood counts return to a normal or more normal level.

Example 1

Rhodium Catalysed Synthesis of Enatiomerically Enriched trans-2-Alkoxy-1,2-dihydro-naphthalen-1-ols

[0142] In 1973, Hogeveen and Middelkoop reported a [Rh(CO)2Cl]2 catalyzed ring opening reaction of 5 by reaction with methanol giving 6. (Hogeveen, H., et al., Tetrahedron Lett. 190:1 (1973)) Subsequently, Ashworth and Berchtold reported the stereochemistry of this reaction to be cis as shown after the formation of a Diels-Alder adduct with 9 (scheme 1) (Ashworth, R. W., et al., Tetrehedron Lett. 339 (1977)). This stereochemistry is in keeping with the observation of exo attack by nucleophiles with other oxabicyclic starting materials (Lautens, M., Synlett 179 (1993)). Hogeveen and-Middelkoop also reported that the reaction was regioselective when only one of the bridgehead positions was substituted, that is 11 gave only regioisomer 12.

[0143] When 13 (Stiles, M., e al., J. Am. Chem. Soc. 82:3802 (1960)) was subjected to the Hogeveen and Middelkoop conditions, no reaction was observed. However, by changing the solvent system to a 1:1 mixture of trifluoroethanol (TFE):methanol and by increasing the temperature to 60° C., the desired product 14 was isolated in 70% yield. Remarkably, the stereochemistry of 14 was trans as proven by comparison with authentic samples of both stereoisomers of dimethoxytetrahydronaphthalene 15 (eq. 2) (The cis isomer of 15 was prepared by reaction of 1,2-dihydronaphthalene with OSO4 followed by methylation with dimethylsulfate (DMS). The trans isomer was prepared by epoxidation of 1,2-dihydronaphthalene followed by ring opening with hyroxide and dimethylation with DMS).

[0144] Given the ability of this reaction to set tip two stereocentres with complete regio and stereocontrol, the possibility of rendering it asymmetric was investigated. A serious drawback of the existing catalyst [Ph(CO)2Cl]2, however, was that the addition of phosphine ligands completely inhibited the reaction. By changing to a rhodium source possessing the more labile COD ligand, [Rh(COD)Cl]2, it was possible to examine the catalytic ability of several chiral phosphine ligands. Not all rhodium-ligand combinations performed equally well. DPPE and BINAP did not produce the desired product, and phosphites resulted in poor yields. DPPF was very efficient, however, giving 14 in 88% yield. One advantage of DPPF is that a number of chiral analogues have been prepared and could be studied to determine enantioselectivity. JOSIPHOS ligands (Togni, A., et al., J. Am. Chem. Soc. 116:4062 (1994)) were among the chiral ligands examined which gave the most promising results. For example, PPF-PtBu, 16 gave 14 in 84% yield and 86% ee at 60° C. The ee could be significantly improved to 97% when the reaction temperature was increased by 20° C.

[0145] These reactions were typically run as a 1:1 mixture of MeOH:TFE under a nitrogen atmosphere which gave 13 accompanied by small amounts of naphthol. In neat trifluoroethanol under a nitrogen atmosphere, naphthol is the major product with less than 5% conversion to the trifluoroethanol ring-opened product. Remarkably, this is not the case when the reaction is run under a carbon monoxide atmosphere. In the presence of CO, the reaction with neat TFE gives the TFE ring-opened product 17 in 70% yield after 3 hours. A colour change of the solution, from yellow to red was observed, suggesting that the CO was interacting with the rhodium metal. When the reaction was performed under asymmetric conditions using PPF-PtBu2, 17 was obtained in 70% yield and 98% ee indicating that the ligand remains bound to the metal even if CO binding has occurred (table 1).

[0146] Reactions run in alcohols other that TFE proceeded at a much slower rate. When the solvent was changed to THF, the reaction worked equally well with a broad range of alcohols under racemic and enantioselective conditions, and only five equivalents of the alcohol were required. THF also allowed the use of very low catalyst loadings, typically in the range of 0.125 mmol % of [Rh(COD)Cl]2 and 0.25 mol % of 16. While TFE would only add to give 17 when the reaction was run under a CO atmosphere in neat TFE, this was not the case in THF. When THF was used as the solvent, TFE added efficiently under an inert nitrogen atmosphere to give 17 in 70% yield and 98% ee. Even the very weakly nucleophilic hexafluoroisopropanol (HFI) added under these reaction conditions to give 23 in 90% yield and 93% ee (table 2).

[0147] In order to investigate the effects of substituents on the aromatic ring of 13, difluoro (24), methylenedioxy (25), and dimethyldibromo (26) substrates were prepared (Hart, H., Tetrahedron 43:5203 (1987)) and reacted them under the standard conditions. All gave the corresponding ring opened products in good yields and excellent ee's (chart 1) indicating that this reaction is not sensitive to remote substitution or electronic effects on the aromatic ring.

[0149] To furan (100 ml, 1.37 ml) in DME (100 ml) at 50° C. in a flame dried three neck flask with a reflux condenser and two addition funnels attached was added simultaneously over two hours a solution of anthranilic acid (27.5 g, 200 mmol) in DME (100 ml) and a separate solution of isoamylnitrite (40 mL, 298 mmol) in DME (50 mL). Upon completion of addition, the reaction was allowed to stir at 50° C. for 30 min until no further gas was evolved. The reaction mixture was then cooled to room temperature and portioned between Et2O and saturated K2CO3 and the aqueous layer was extracted three times with Et2O. The combined organic layer were washed with brine, dried over MgSO4 and concentrated. Bulb to bulb distillation gave 13 (18.5 g, 64%) as a white solid. The spectral data correspond well with the literature data.17
