We present a new, unified approach for the transformation of benzylic and allylic alcohols, aldehydes, and ketones into boronic esters under electroreductive conditions. Key to our strategy is the use of readily available pinacolborane, which serves both as an activator and an electrophile by first generating a redox-active trialkylborate species and then delivering the desired deoxygenatively borylated
我们提出了一种新的、统一的方法,用于在电还原条件下将
苄醇和
烯丙醇、醛和酮转化为
硼酸酯。我们策略的关键是使用容易获得的
频那醇硼烷,它首先生成氧化还原活性三烷基
硼酸盐物质,然后提供所需的脱氧
硼酸化产物,从而既充当活化剂又充当亲电子试剂。该策略适用于各种底物,并且可用于复杂分子的后期功能化。
