Open Data Verified Data
L-proline was dissolved in an aqueous sodium hydroxide solution, cooled in an ice bath, and reacted by adding benzyl chloroformate in portions with vigorous stirring to obtain N-benzylcarbonyl-L-proline. N-benzylcarbonyl-L-proline was dissolved in a solution of dichloromethane, isobutylene and concentrated sulfuric acid, and the reaction was worked up to give N-benzylcarbonyl-L-proline tert-butyl ester. L-proline tert-butyl ester was obtained by dissolving it in absolute ethanol and hydrogenating it under normal pressure using palladium on carbon as catalyst. L-proline tert-butyl ester is dissolved in dichloromethane, dicyclohexylcarbodiimide is added, and then dichloromethane solution of 3-acetylmercapto-2-methylpropionic acid is added, after completion of the reaction, N-(3-acetylmercapto-2-methylpropionyl) L-prolyamino tert-butyl ester was obtained. This was added to a mixed solution of anisole and trifluoroacetic acid, the reactant was precipitated with diethyl ether-hexane, the precipitate was dissolved in acetonitrile, dicyclohexylamine was added, and the dicyclohexylamine salt of the (S.S.) L-proline derivative was worked up. The salt is in a mixed solution of potassium hydrogen sulfate and acetic acid ethanol, the separated organic layer is washed with water, concentrated to dryness, and the obtained material is crystallized with ethyl acetate-hexane to obtain optically active (S.S.) l-N-(3-acetyl thiol -2- D-methyl propionyl)-L-proline. The Proline derivative was dissolved in a solution of ammonia in methanol and maintained at room temperature, and the solvent was distilled off under reduced pressure. The resulting material was dissolved in water, chromatographed on an acid type ion exchange resin, and further treated to give captopril. Or a-based acrylic acid and thioacetic acid addition, to obtain a-methyl-p-acetyl mercaptoacetic acid, and then chloride sulfoxide chlorination to acid chloride, directly and proline in the role of sodium hydroxide, N-(3-acetylmercapto-2-methylpropionyl)-L-proline was obtained, and optical resolution was carried out by using dicyclohexylamine as a salt to obtain (S,S) body, and then the acetyl group was removed by ammonolysis, captopril was obtained.
