A NEW METHOD FOR ENANTIOSELECTIVE SYNTHESIS OF β-HYDROXY-α-AMINO ACIDS

Abstract
Highly optically active threo-β-hydroxy-α-amino acids were obtained by the successive treatment of the chiral hydroxy imine 1, prepared by the condensation of t-butyl glycinate with a chiral ketol 3, with methylmagnesium iodide, potassium diisopropylamide and aldehyde.
