NEW EFFICIENT SYNTHESIS OF 3(5)-CARBOMETHOXY-4-ARYLPYRAZOLES FROM 3-ARYL-2,3-DEHYDROAMINO ACID DERIVATIVES

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

Action of Diazomethane on Methyl (Z(or E))-2-(Acylamino)cinnamates. A New Route to Methyl (Z)-2-(Acylamino)-3-methylcinnamates

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
