and medicinal chemistry. However, coupling reactions of cyclobutanols involving β-carbon elimination to construct C(sp3)–C(sp3) bonds have scarcely been developed. Here, we demonstrate a highly enantioselective Pd-catalyzed intermolecular C(sp3)–C(sp3) coupling reaction of a broad range of cyclobutanol derivatives and unactivated alkenes, allowing convenient access to a series of chiral benzene-fused
小应变环的碳-碳键的过渡金属催化活化在合成和药物化学中具有广泛的应用。然而,涉及β-碳消除以构建C(sp 3 )–C(sp 3 )键的环丁醇的偶联反应几乎没有被开发出来。在这里,我们展示了一种高度对映选择性的 Pd 催化的分子间 C(sp 3 )–C(sp 3 ) 偶联反应,广泛的环丁醇衍生物和未活化的烯烃可以方便地获得一系列手性苯稠合环状化合物。高度区域选择性、化学选择性和对映选择性。
