challenging but synthetically indispensable approach to α-branched carbonyl motifs that are widely represented among drugs, natural products, and synthetic intermediates. Here, we describe a simple approach to generation of boron enolates in the absence of strong bases that allows for introduction of both α-alkyl and α-aryl groups in a reaction of readily accessible 1,2-dicarbonyls and organoboranes.

在α-碳上构建CC键是一种具有挑战性但在合成中必不可少的方法,可用于药物,天然产物和合成中间体中的α-支链羰基。在这里,我们描述了一种在不存在强碱的情况下生成烯醇硼的简单方法,该方法允许在易于获得的1,2-二羰基与有机硼烷的反应中引入α-烷基和α-芳基。避免使用非选择性,强碱性和亲核试剂,可以在亲电体存在的情况下进行反应,亲电体会拦截中间的硼烯醇化物,从而在三组分过程中产生两个新的α-C-C键。
