Abstract

Huisgen reaction of nitrile oxides and nitrile imines generated  in situ in the presence of N-benzylmaleimide afforded regiospecifically the corresponding  cis-3-aryl-5-benzyl-3a,4,6,6a-tetrahydro-4H,6H-pyrrolo[3,4-d]isoxazoline-4,6-diones and  cis-3-aryl-5-benzyl-1-(2',4'-dibromo-
phenyl)-3a,4,6,6a-tetrahydro-1H,5H-pyrrolo[3,4-c]pyrazole-4,6-diones in good yield.
