Popis: Intramolecular cyclization of [N-benzyl(arylglyoxylimidoyl)]ketenes generated upon thermal decarbonylation of 4,5-diaroyl-1-benzylpyrrole-2,3-diones is accompanied by redox processes to form 3-aroyl-5-aryl-4H-furo[3,2-c]isoquinolin-2-ones and 3-benzoyl-4-benzylamino-5-phenyl-5H-furan-2-one (1). The molecular and crystal structure of compound 1 was studies by X-ray diffraction analysis. Under conditions of thermolysis, the starting pyrrole-2,3-diones are partially reduced to 4,5-diaroyl-1-benzyl-3-hydroxy-5H-pyrrol-2-ones.
