Abstract:
A series of six new 3-imidazo[1,2-a] pyridine furan bound type tris-heterocycles were synthesized by Ultrasound Irradiation (USI) assisted Groebke-Blackburn-Bienaymé reaction (GBBR), by employing ammonium chloride (10 mol%) as a catalyst in excellent yields (80-93%) under green conditions. This efficient and mild protocol has silent features such as green inexpensive and easily available catalyst and solvent at room temperature.
