Intermolecular Reductive Heterocyclization of Potassium 2-Acyl-1,1,3,3-tetracyanopropenides
摘要:
2-Acyl-1,1,3,3-tetracyanopropenides undergo intermolecular reductive heterocyclization under the action of mercaptoethanol or sodium borohydride, resulting in the formation of 2-[5-amino-4-cyano-2-alkyl(aryl)furan-3(2H]-ylidene) malononitriles in high yields and excellent purities, These are of interest as potential precursors to organic nonlinear optical (NLO) materials and prospective antibiofilm antimicrobial agents.

2-Acyl(aroyl)-1,1,3,3-tetracyanopropenides reacted with hydrogenhalides along two concurrent pathways with formation of furan or pyridine derivatives. The reaction in butan-2-ol afforded 2-amino-4-acyl-(aroyl)-6-halopyridine-3,5-dicarbonitriles, whereas the major products in the reactions with HCl and HBr in aqueous solution were the corresponding 2-(5-amino-2-aryl-2-chloro(bromo)-4-cyano-2,3-dih
