Abstract: A highly efficient and environmentally benign protocol for the synthesis of 8-amino-6-aryl-1,2-dihydro-2-oxo-6H-pyrano[2,3-e]benzoxazole-7-carbonitrile derivatives by one-pot three-component coupling reacting of aromatic aldehydes, malononitrile and 4-hydroxy-2(3H)-benzoxazolone under reflux condition has been developed in aqueous media using Na₂O-Al₂O₃-P₂O₅ glass-ceramic system.
