A new general method of synthesis of optically pure α- amino esters was elaborated during studies on the reaction of organocuprates with tosyl and halogeno derivatives of L-serine and L-homoserine.

The lithium diorganocuprate reactions with L-serine derivatives are studied. Retention of configuration, or at least a high enantiomeric excess (>80%) of the formed α-amino esters is observed in all cases. Attempts are made to restrict side-reactions.
