Abstract

The enantiomerically pure (2S,3R)- and (2S,3S)-3-amino-2-hydroxy-4-phenylbutanoic acids (AHPBA) were first obtained from sugar in a chirospecific manner. Additionally, the obtained (2S,3R)-AHPBA 1 was easily applied to the synthesis of (-)-bestatin.

The chiral aminoalcohol (19) has been obtained using the same reaction conditions in Scheme [2] .
