Abstract Phenacyl-malononitrile derivatives 1a,b react with dimethyl formamide dimethyl acetal (DMFDMA) in refluxing toluene to afford the enaminones 2a,b respectively. Compounds 2a and 2b react with the aromatic amines (aniline, p-toluidine, p-anisidine) in refluxing ethanol to afford the pyrroles 4a–f and with anthranilonitrile and methyl anthranilate to afford the pyrrolo[1,2-a]quinazolines 5a,b
