NEW SYNTHESIS OF PROTECTED α-DEHYDRO α-AMINOACIDS FROM SUBSTITUTED OXAMIC ACID

Article abstract of DOI:10.1016/S0040-4039(00)82078-X

The condensation of a phosphorus ylid with t-butoxalyl iminoether gives 3-carbobutoxy 2-aza 1,3-dienes ; subsequent reaction with hydriodic acid provides protected α-dehydro α-amino acids.
