Abstract

This invention relates to a process for preparing optically active carboxylic acids by oxidizing an optically active aldehyde with a peracid in the presence of an amine and/or amine N-oxide catalyst selected from the group consisting of a substituted or unsubstituted alkyl amine, alkyl amine N-oxide, aromatic amine, aromatic amine N-oxide, heterocyclic amine, heterocyclic amine N-oxide and mixtures thereof, to produce the optically active carboxylic acid. Such optically active carboxylic acids have utility for example as pharmaceuticals.
