β-hydroxy ketone O-benzyl oximes with lithium aluminum hydride in the presence of sodium or potassium methoxide afforded the corresponding syn-β-amino alcohols in highly stereoselective manner. A lythraceae alkaloid, lasubine II, was synthesized stereoselectively by applying this method.

ketones with O-benzylhydroxylamine hydrochloride gave a mixture of stereoisomers of the corresponding O-benzyloximes. The mixture of the both isomers was reduced with lithium aluminum hydride in the presence of sodium or potassiummethoxide to afford syn-1,3-amino alcohols in a highly stereoselective manner.

syn-1,3-Amino alcohols are prepared in good yields by the stereoselectivereduction of β-hydroxy ketone-O-benzyloximes derived from acyclic β-hydroxy ketones with lithium aluminiumhydride.
