In the presence of a catalytic amount of diphenylboryl triflate, the kinetic resolution of cyclic dl-dicarboxylic anhydrides is effectively achieved by the use of diphenylboric ester of (R)-2-methoxy-1-phenylethanol as the chiral source.
Highly Efficient Asymmetric Esterification of Cyclic meso-Dicarboxylic Anhydrides Catalyzed by Diphenylboryl Triflate
Ohshima, Masahiro,Mukaiyama, Terauki
, p. 377 - 380 (2007/10/02)
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.
