In this work, we demonstrated a novel electrochemical oxidative cyclization for synthesis of flavone from 2’-hydroxychalcone using an inexpensive using low toxic NaI as mediator/electrolyte without external additives in EtOH/water solvent. The key features of this reaction include its broad substrate scope, scalability, ability to operate with benign solvent at room temperature, and no requirement
在这项工作中,我们展示了一种新型电化学氧化环化方法,用于从 2'-羟基查耳酮合成黄酮,使用廉价的低毒 NaI 作为介体/电解质,无需外部添加剂,在乙醇/水溶剂中。该反应的主要特点包括底物范围广泛、可扩展性、能够在室温下使用良性溶剂进行操作,并且不需要强氧化剂和外部添加剂。
