Abstract

A method for the resolution of .alpha.-tertiary carboxylic acid esters by partial hydrolysis is disclosed. The partial hydrolysis is carried out by contacting the esters with an aqueous solution in the presence of a lipase derived from Candida lipolytica, and the hydrolysis product is separated from unreacted starting material to obtain the hydrolysis product or the unreacted starting material in enantiomerically enriched form.
