here. This strategy enables the enantioselective construction of chiral allylic sulfones from simple α-chlorosulfones and vinyl bromides. The mild reaction conditions lead to excellent functional group compatibility, as evidenced by the broad substrate scope and tolerance of complex bioactive molecules. Our preliminary mechanistic study suggests that this enantioselective vinylation process operates through
本文描述了 α-氯砜与溴乙烯的镍催化对映收敛还原交叉偶联。该策略能够从简单的 α-氯砜和乙烯基溴化物中选择性地构建手性烯丙基砜。温和的反应条件导致了优异的官能团相容性,这可以通过广泛的底物范围和复杂的生物活性分子的耐受性来证明。我们的初步机理研究表明,这种对映选择性乙烯基化过程是通过自由基中间体进行的。
