Method for racemization of non-racemic 3-oxocyclopentane or 3-oxocyclohexane carboxylic acids and their esters with C1-C6 alcohols

摘要

The racemates are obtained from non-racemic 3-oxocyclopentane or 3-oxocyclohexane carboxylic acids or their esters by esterification and ketalization of the non-racemic acid with orthoformic acid ester in an alcohol, racemization and hydrolysis of the product obtained with an alcoholate and isolation of the racemate.
