N-Imidoyl sulfoximide (7) reacted with diphenylcyclopropenone (2) at 130 degree C to yield a mixture of 1,2-disubstituted 5,6-diphenyl-4(1H)-pyrimidinone (6) and N-(4-oxo-2-pyrrolin-5-yl)sulfoximide (10), which might be formed by left bracket 3 plus 3 rig

Benzocinnolinium-5-(N-acylimides) (6; R = Ph, OEt, or Me) give benzocinnoline and 2-substituted-4,5-diphenyloxazin-6-ones (7) on reaction with diphenylcyclopropenone.In contrast, the related benzocinnolinium-5-(N-benzimidoimides) (11; R = H, Ph, or p-tolyl) give stable adduct (12), which on pyrolysis yield benzocinnoline and 1-substituted-2,5,6-triphenylpyrimidin-4-ones.
