Tandem reduction-alkenylation of Schiff base derivatives of optically pure α-amino esters, followed by catalytic osmylation of the resulting allylic threo-amino alcohols provides a facile route to galacto- and fuco-amino sugar derivatives. Subsequent cyclization (reductive amination) provides biologically interesting aza-sugar derivatives in high yield with excellent stereocontrol.
