A GeCl2-mediated addition reaction of α-(N-phthaloylamino)allylic stannane to aldehydes was achieved to give 1,2-amino alcohol derivatives in high anti-selectivity. Various types of aromatic and aliphatic aldehydes were applicable. The synthesized N-phthaloylamino alcohols were smoothly transformed to aminoalcohols by conventional methods with no loss of stereochemistry.

corresponding alpha-aminoorganolithiums. Reactions of these organolithiums with aromaticaldehydes provides N-protected beta-amino alcohols with diastereoselectivities up to >99:1 anti/syn; with aliphaticaldehydes, diastereoselectivities were typically 1:1. Diastereoselectivities varied depending on the amount of aldehyde used. The N-protected beta-amino alcohols could be deprotected to primary amines
