Reactions of Cyclopropenones with Azomethines; VII, Diphenylcyclopropenone and Cyclic Amidines: Synthesis of Bi- and Tricyclic Pyrrolinone Derivatives Reaction of diphenylcyclopropenone (1) with cyclic amidines 2 or 10-13 gives rise to bi- and tricyclic pyrrolinone derivatives of different structural types (3 or 14-17), which can be transformed in simple sequences to pyrrolinoneannellated heterobi- and tricyclic compounds (7, 18-21).
