Abstract
The transformation of a racemic mixture under the influence of a chiral reagent or catalyst is discussed in the case where regioisomeric products are obtained. The general relationships correlating the ee's and the quantities of the various products are given.
The special case of asymmetric Baeyer-Villiger oxidation of racemic ketones is taken as an example. Sometimes regioisomeric products are derived from opposite enantiomers, which implies that the re- gioselectivity of a reaction on an enantiomerically pure starting material will be controlled by the absolute configuration of the chiral reagent or catalyst.
