Abstract
Addition of dialkyl phosphites to Schiff bases derived from (R)-2-methoxy-1-phenylethylamine or (R)-phenylglycine methyl ester afforded (1R, 1′R)-1-arylphosphonoglycine derivatives with moderate to high diastereoselectivity. The influence of catalysts and solvents and the structural effects of the substrates on this stereochemical process were reported.
