摘要 : An efficient and green method for the synthesis of 2-amino-3-cyano-4-aryl-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene and hydroxyl naphthalene-1,4-dione derivatives using triethylammonium hydrogen sulfate ([Et3NH][HSO4]) as Bronst... 展开 An efficient and green method for the synthesis of 2-amino-3-cyano-4-aryl-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene and hydroxyl naphthalene-1,4-dione derivatives using triethylammonium hydrogen sulfate ([Et3NH][HSO4]) as Bronsted acidic ionic liquid for the three-component condensation reaction under ambient and solvent-free conditions is described. Simple procedures, high yields, short reaction times, and reusability of the catalyst are advantages of this protocol. 收起
