A nickel-catalyzed asymmetric decarboxyarylation of NHP esters via reductive cross-coupling has been established. Utilizing the NHP of amino acid esters as radical precursors furnishes a new protocol in which structurally diverse chiral benzylamines could be accessible. This method has demonstrated excellent catalytic efficiency, high enantioselective control, mild conditions, and good functional group
已经建立了镍催化的 NHP 酯通过还原交叉偶联的不对称脱羧基反应。利用氨基酸酯的 NHP 作为自由基前体提供了一种新的方案,其中可以获得结构多样的手性苄胺。该方法具有优异的催化效率、高对映选择性控制、温和的条件和良好的官能团耐受性,从而能够实现生物活性分子和药物的后期修饰。
