Efficient One-Pot Synthesis of 4-Aryl-3-cyano-2,5-dihydro-1H-indeno[1,2-b]pyridin-2-one and 4-Aryl-3-cyano-1,2,5,6-tetrahydrobenzo[h]quinolin-2-one Derivatives Under Solvent-Free Conditions

Abstract 4-Aryl-3-cyano-2,5-dihydro-1H-indeno[1,2-b]pyridin-2-one and 4-aryl-3-cyano-1,2,5,6-tetrahydrobenzo[h]quinolin-2-one have been prepared from indan-1-one or 3,4-dihydronaphthalen-1(2H)-one, aromatic aldehydes, 2-cyanoacetamide, in the presence of sodium hydroxide under solvent-free conditions. The rapid and facile method produced products in high yields.
