An efficient method for the synthesis of 4-hydroxy-3-formylideneamino-l H/methyl/phenylquinolin-2-ones by the condensation of corresponding 4-hydroxy-3-formyl-l///methyl/phenylquinolin-2-one with substituted anilines/aliphatic primary amines is reported. The carboxaldehyde in turn is prepared starting either from substituted anilines or benzoic acid. The structures of compounds are established by the elemental analysis and spectral data.

Studies on aspects of the mechanism of our general synthesis of polycyclic heteroaromatic compounds suggest that the reaction sequence outlined in Scheme 2 is followed.Under the conditions of our synthesis, the ortho-rearrangement (8) --> (9) is preferred to the para-rearrangement which is known to occur in acid conditions.Aniline Mannich bases (29) are converted to benzacridines (30) in an intermolecular reaction.The synthesis appears to be restricted to substrates where the putative intermediate (9) is not part of an amide group.In the course of these studies effective syntheses of the tricyclic compounds (24) and (25) have been discovered.
