Abstract
The N-Benzyl imines derived from 2,3-di-O-benzyl-D-glyceraldehyde and 2,3-di-O-isopropylidene-D-glyceraldehyde reacted with phenylmagnesium bromide to afford fully protected aminodiols with total diastereoselec tivity. The stereochemical course of the addition reaction depends on the nature of the O-protecting group. These compounds can be easily tr ansformed to enantiomerically pure (R) and (S)alpha-phenylglycine.
