In the presence of a catalytic amount of diphenylboryl triflate, cyclic meso-dicarboxylic anhydrides are esterified by diphenylboric ester of (R)-2-methoxy-1-phenylethanol in a highly stereoselective manner, and, after the treatment with diazomethane, the chiral diesters are obtained with high diastereomeric excess.
