Diphenylnitrilimine 5 adds regioselectively to the carbon-carbon double bond of methyl β-aryl-N-benzoyl-α,β-didehydroalaninates 3 to afford the pyrazoline derivatives 6.The regiochemistry of the latter cycloadducts was evidenced chemically by their conver

The title compounds 5 can be easily obtained by two alternative procedures: 1,3-dipolar cycloaddition to benzamidocinnamates 3 prepared by methanolysis of the corresponding oxazolones 1 or methanolysis of the spirooxazolones 4 synthesized by 1,3-dipolar c
1,3-Dipolar Cycloaddition Reactions of 2-Phenyl-4-arylidene-5(4H)-oxazolones with Nitrile Imines. A Reinvestigation of the Regiochemistry of the 1,3-Dipolar Cycloaddition Reactions of 2-Phenyl-4-arylidene-5(4H)-oxazolones with Nitrile Oxides
