Reactions of 4-(p-Methylbenzoyl)-5- (p-methylphenyl)furan-2,3-dione with Various Anilides

Abstract

4-(p-Methylbenzoyl)-5-(p-methylphenyl)furan-2,3-dione (1) reacts with acetanilides (3a-f) under different conditions and gives open-chain dibenzoylacetic acid derivatives 4a,b, 5c-f. It has been demonstrated that with the variation in reaction conditions, the reaction changes leading to different products. All the newly synthesized compounds were characterized by elemental analysis, IR, ¹H and ¹³C NMR spectral data. All were compared with their previous analogues.
