α-Amino esters 7 are prepared in good chemical yield and enantiomeric excess (53-86%) by ethanolysis and subsequent debenzylation of the α-amino nitriles 5 obtained by regio- and stereocontrolled ring opening of N-benzyl-2-phenylglycinol-derived oxazolidines 4 (2-alkyl-3-benzyl-4-phenyloxazolidines) with diethylaluminum cyanide.
