Abstract
It is shown that in the presence of crude PPL (Sigma type II) carbonic acid diesters ent-2 can be hydrolyzed enantioselectively. In contrast to hydrolysis of carboxylic esters working under pH-stat conditions is not necessary anymore. Vice versa, the enantioselective acylation of glycidol with carbonic acid derivatives, e.g. carbonic acid anhydrides, proceeds less selectively.
