cobalt‐catalyzed hydroacylation of 1,6‐enynes with exogenous aldehydes in a domino sequence to construct enantioenriched ketones. The products were obtained in good yields with excellent regio‐, diastereo‐, and enantioselectivity. Furthermore, the chiral products served as valuable precursors to access complex spirocyclic scaffolds with three contiguous stereocenters. The asymmetric hydroacylation process exhibited
我们报告了多米诺骨牌中外源醛的1,6-烯炔的钴催化加氢酰化反应,以构建对映体富集的酮。获得的产品收率高,具有出色的区域选择性,非对映异构性和对映选择性。此外,手性产物是进入具有三个连续立体中心的复杂螺环骨架的有价值的前体。不对称加氢酰化过程没有CH交叉和KIE,因此表明CH键断裂不涉及营业额限制步骤。
