摘要：

A series of seventeen novel 3-imidazo[1,2-alpha]pyridine carbazoles bound type bis-heterocycles were synthesized by Ultrasound irradiation (USI) assisted Groebke-Blackburn-Bienayme reaction (GBBR), by employing ammonium chloride (10 mol%) as a catalyst in excellent yields (90-96%). This new, efficient and mild protocol has silent features such as green inexpensive and easily available catalyst and solvent at room temperature. (C) 2018 Elsevier Ltd. All rights reserved.
