universal building blocks for structurally diverse phosphine compounds. However, the synthesis of alkynylphosphines via direct P–C bond formation was unprecedented. Here, we report an efficient method for the synthesis of P-stereogenic alkynylphosphines with high enantioselectivity via a Ni-catalyzed asymmetric cross-coupling reaction. The reaction could tolerate a variety of functional groups, affording
由于三键的高反应性,P-立体炔基膦可以很容易地衍生化,作为结构多样的膦化合物的通用构建单元。然而,通过直接形成P-C键来合成炔基膦是前所未有的。在这里,我们报告了一种通过镍催化的不对称交叉偶联反应合成具有高对映选择性的 P-立体炔基膦的有效方法。该反应可以耐受多种官能团,提供可以转化为有用的膦衍生物的产物。
