Synthesis of optically active hydroxy amino acids via 2-O-benzylglyceraldehyde N-[(R)-1-phenylethyl]imine

Abstract
N-Boc esters of 3-phenylisoserine D, norstatine E, statine F, ‘methylsilastatine’ G and homostatine H are prepared in 4 to 5 steps from 2-O-benzylglyceraldehyde N-[(R)-1-phenylethyl]imine 1.
