versatile intermediates in organic synthesis. Herein, we present an ‘ate-mediated allylic substitution’ (AMAS) approach to allylic boronates. Bifunctional vinylboroate/ allylic acetate esters react with Grignard reagents to form tertiary allylic boronates via an AMAS reaction. We demonstrate that the method tolerates a wide range of substrates and Grignard reagents.
烯丙基硼酸酯是有机合成中的通用中间体。在此,我们提出了一种“ate 介导的烯丙基取代”(AMAS)方法来处理烯丙基硼酸盐。双功能乙烯基硼酸酯/烯丙乙酸酯与格氏试剂反应,通过 AMAS 反应形成叔烯丙硼酸酯。我们证明该方法可以耐受多种底物和格氏试剂。
