A facile and convenient three-component coupling protocol for the synthesis of pyrano and furoquinolines
Ceric ammonium nitrate (CAN) catalyzes efficiently the coupling of anilines, benzaldehydes and 3,4-dihydro-2H-pyran or 2,3-dihydrofuran to form the corresponding pyrano or furoquinolines in short reaction times and in high yields.
