An efficient method for the preparation of optically active derivatives of γ-amino-butenoic acids and their cyclic derivatives, 2-amino-pyrrolin-4-ones, from α-amino acids is described. Partial racemization accompanies the formation of initial unsaturated γ-amino-β-hydroxy esters 5–8, as determined by chiral HPLC.
