Non racemic 3 - oxo cyclopentane carboxylic acid or 3 - oxo cyclohexane carboxylic acid or manner null for racemizing the ester of those C1-C6

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.
