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

The reaction of diphenylcyclopropenone with R1N=C(R2)X (2) (R1, R2=alkyl, aryl, X=MeO, EtO, MeS, or Me2N) gave 2-pyrrolin-4-one (3) in good yield.The less reactive carboximidothioate (2, R1=4-MeC6H4, R2=Ph, X=MeS) yielded isomeric 3-pyrrolin-2-one together with 3.
