Hydrolysis of several α-alkyl-α-aryloxyacetic acid methyl esters and of α-methyl-α-(n-propyl)-α-(p-chlorophenoxy)acetic acid methyl ester were performed in the presence of Candida cylindracea lipase. The α-alkyl-α-aryloxyacetic acid methyl esters and α-methyl-α-(n-propyl)-α-(p-chlorophenoxy)acetic acid methyl ester were incubated in buffer phosphate (pH 7-8). The reaction mixture, containing the unreacted ester and corresponding acid, showed enantiomeric excesses (ee) up to 81%. The extent of conversion was quite low for the α-methyl-α-(n-propyl)-α-(p-chlorophenoxy)acetic acid methyl ester, the corresponding acid was obtained with ee > 98%.
