Abstract
The stereocontrolled nucleophilic addition of lithium trimethylsilyl a cetylide to the N-benzyl nitrone (BIGN) derived from 2,3-O-isopropylid ene-D-glyceraldehyde, followed by oxidative cleavage of the ensuing pr opargyl hydroxylamines resulted in an efficient stereodivergent synthe sis of fully protected epimeric N-hydroxy alpha-amino esters 8 and 13 as well as the corresponding cw-amino esters 9 and 14.
