Chiral homoallylic vicinal diols are found in many bioactive compounds and are among the most versatile functional groups in organic chemistry. Here, we describe an asymmetric carbonyl allylation of aldehydes with allyl ethers proceeding via allylic C-H borylation enabled by palladium and chiral phosphoric acid sequential catalysis, providing facile access to homoallylic vicinal anti-diols in high
手性同烯丙基邻二醇存在于许多生物活性化合物中,是有机化学中用途最广泛的官能团之一。在这里,我们描述了具有烯丙基醚在进行醛的不对称羰基烯丙基经由烯丙基的CH硼化由钯和手性磷酸顺序催化启用,提供对以高产率和具有优异的立体选择性高烯丙基邻抗二醇容易访问。该协议使 aigialomycin D 的全合成能够在 7 个步骤内完成。
