titleOfInvention | Production of optically active cyclopentenolone compound |
abstract | PURPOSE: To obtain the titled compound having the absolute configuration opposite to that of the starting optically active sulfonic acid ester, by hydrolyzing a mixture of said optically active ester and an optically active carboxylic acid having opposite absolute configuration to the sulfonic acid ester, under acidic condition. n CONSTITUTION: A mixture of (A) an optically active sulfonic acid ester of formula I (* is asymmetric carbon; R 1 is H or lower alkyl; R 2 is lower alkyl, lower alkenyl, etc.; X is lower alkyl, etc. which may be substituted with halogen) and (B) an optically active carboxylic acid ester of formula II (R 3 is lower alkyl) having opposite absolute configuration to the sulfonic acid ester, is hydrolyzed under acidic condition to obtain the objective optically active compound of formula III having opposite absolute configuration to the compound of formula I . The objective optically active isomer can be produced in high yield and purity without using any separation treatment, by the hydrolysis under acidic condition. n COPYRIGHT: (C)1985,JPO&Japio |
