threo and erythro diastereoisomers of the constrained amino acid (βMe)Phe can be obtained separately on a multigram scale through a three-step synthesis from the corresponding Z and E isomers of 2-phenyl-4(α-phenylethylidene)-5(4H)-oxazolone. The 5(4H)-ox

The methyl Z-2-acetamido(or benzamido)-3-aryl-2-butenoates (Z-9a-e, Z-10a-e) were obtained by two alternative procedures: stereospecific opening of Z-2-methyl(or phenyl)-4-(α-arylethylidene)-5(4H)-oxazolones (Z-7a-e, Z-8a-e) and stereospecific homologatio

Diazomethane reacts with methyl (Z(or E))-2-acetamido(or benzamido)cinnamates (1,2) to afford regio- and stereospecifically (Z(or E))-4-phenyl-3-acetamido(or benzamido)-3-carbomethoxy-Δ1-pyrazolines (3,4). 3Z and 4Z undergo pyrolysis to afford
