Process for racemization of optically active 4-phenylbutanoic acid esters |
| abstract |
A process for the racemization of optically active 4-phenylbutanoic acid esters which comprises treating optically active 4-phenylbutanoic acid esters of the general formula (I) <CHEM> wherein R<1> represents a hydroxy group, a hydroxy group protected by a vinyl ether, or a lower acyloxy group and R<2> repesents a lower alkyl group with a base selected from the group consisting of alkali metal alcoholates, alkali metal hydrides, and alkali metal amides is provided. |
