Both diastereomers of 3-amino-2-hydroxyalkanoic acid derivatives were synthesized selectively by LDA-induced reaction of N-methoxycarbonyl-1-methoxyamines with O-protected N,N-dimethylglycolamides. The inversion of the diastereoselectivity was highly achieved by 1) selecting the O-protecting groups and 2) the addition of Ti(OPr-i)(4).
