Abstract
The condensation reactions of 6,8-dimethyl-4-oxo-4H-1-benzopyran-3- carboxaldehyde (1) with equimolar amounts of ethyl 2-amino-4-(4-chlorophenyl)-5- cyano-1-[(5,6-diphenyl-1,2,4-triazin-3-yl)amino]-6-oxo-1,6-dihydropyridine-3- carboxylate (2) at different reaction conditions gave different chromanone and chromenone products 3, 4, 5. Also, the condensation reactions of compound 1 with ethyl 5-cyano-1,2-diamino-4-(3-nitrophenyl)-6-oxo-1,6-dihydropyridine-3- carboxylate (6) in absolute ethanol, dry benzene, acetic acid, and/or dry xylene gave a variety of products 7, 8, 9, 10 depending on the solvent used. © 2014 HeteroCorporation.
