    摘要: A process for the production of medrogestone, in which, in an intermediate step, the solvate 3.beta.,5.alpha.,6.beta.-trihydroxy-6.alpha.,17.alpha.-dimethylpregnan-20-one monomethanolate is obtained as a solid, stable compound by displacing the organic solvent from a solution of of 3.beta.,5.alpha.,6.beta.-trihydroxy-6.alpha.,17.alpha.-dimethylpregnan-20-one with a lower alkanol, and a Diels-Alder adduct of 6-methylene-17.alpha.-methylpregn-4-ene-3,20-dione with maleic anhydride is used as an intermediate for production of the corresponding dicarboxylic acid salt for removal of 6-methylene-17.alpha.-methylpregn-4-ene-3,20-dione contamination of the desired product. Another intermediate, 6.beta.-hydroxy-6.alpha.,17.alpha.-dimethylpregn-4-ene-3,20-dione, has been found to prevent smooth muscle proliferation and is useful in the treatment of atherosclerosis and restinosis.

    摘要: Disclosed herein is a process for obtaining indoline-2-carboxylic acid (or derivatives thereof) comprising the following steps: (a) reducing .alpha.-oxo-2-nitrobenzenepropanoic acid to .alpha.-hydroxy-2-nitrobenzenepropanoic acid, (b) replacing the hydroxyl group of the latter with a chlorine atom utilizing a selected Vilsmeier chlorinating reagent at temperatures of at least 20.degree. C., (c) reducing the nitro group of the resulting .alpha.-chloro-2-nitrobenzenepropanoic acid to obtain .alpha.-chloro-2-aminobenzenepropanoic acid, and (d) cyclizing the latter in aqueous base to form the desired indoline-2-carboxylic acid. Alternately, steps (c) and (d) may be combined in a one pot step by using, for example, a Raney nickel-hydrazine reducing medium.
