Abstract
Acetals of a series of substituted lactic acid derivatives were formed with enantiopure lactol 1. H-1 and C-13 NMR spectroscopic data of the anomerically pure O,O-acetals are compared in order to assign the abs olute configuration of the O-protected lactic acid derivatives and for the determination of enantiomeric excesses. The results are supported by molecular modeling studies.
