3(5)-Carbomethoxy-4-arylpyrazoles can be easily obtained by aromatization with boron trifluoride etherate of 4-aryl-3-acetamido(or benzamido)-3-carbomethoxy-Δ1-pyrazolines synthesized by 1,3-dipolar cycloaddition of diazomethane with 3-aryl-2,3

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
