novel electrochemical method for the synthesis of α,β-epoxy ketones is reported. With KI as the redox mediator, methyl ketones reacted with aldehydes under peroxide- and transition metal-free electrolytic conditions and afforded α,β-epoxy ketones in one pot (36 examples, 52–90% yield). This safe and environmental-friendly method has a broad substrate scope and can readily provide a variety of α,β-epoxy
报道了一种新的合成α,β-环氧酮的电化学方法。用KI作为氧化还原介体,甲基酮在无过氧化物和过渡金属的电解条件下与醛反应,并在一锅中得到α,β-环氧酮(36例,产率52-90%)。这种安全且环保的方法具有广泛的底物范围,并且可以轻松提供以克为单位的多种α,β-环氧酮,以评估其抗癌活性。
