摘　　要：　　In recent years, a wide variety of organic compounds bearing indole fragment have been attracted much attention due to the fact that many of them are pharmacologically and biologically active compounds.[1] Among them β-indolylketones are one of the most significant intermediates for the preparation of natural products such as hapalindole D 1.[2] In recent years, the utilization of multicomponent condensations (MCCs) to generate novel, drug-like scaffolds are replete in current organic reactions due to the fact that products can be prepared directly in a single step and the diversity can be achieved simply by varying the reaction substrates. In continuation of our work to synthesize new β-indolylketones,[3] herein, we report a novel base-induced syntheses of new β-indolylketones via a three-component condensation. Deoxybenzoin as carbonyl compound is introduced into the reaction (Scheme 1), and all the reactions were operated under ultrasound irradiation since the utilization of which can accelerate the progress of many reactions and shorten the reaction time.……
