reaction often necessitated the use of activated ketones or pre-prepared enol intermediates as substrates. In this study, we developed a nickel-catalyzed α-allylation of unactivated cycloketones with allylic alcohols to synthesize chiral cycloketones with an α-quaternary carbon center. The reaction affords the products with 42–97% yields, 72–86% ee, and no additive is needed, and the only by-product is water

金属催化的酮的不对称 α-烯丙基化是通过 C−C 键形成构建立体中心的特别有用的工具。然而,此类反应通常需要使用活化的酮或预先制备的烯醇中间体作为底物。在这项研究中,我们开发了未活化环酮与
