  The first copper‐catalyzed asymmetric cyanation and etherification reactions of enamides have been established, where a carbon‐centered radical adjacent to a nitrogen atom (CRAN) is enantioselectively trapped by a chiral copper(II) species. Moreover, the asymmetric cyanation of vinyl esters was disclosed as well. These reactions feature very mild reaction conditions and high functional group tolerance

  日期：2021.7.7

  direct use of free alcohols without purification of the xanthate esters. Mechanistic studies are consistent with the hypothesis of aryl radicals being formed and initiating the cleavage of the C–O bonds of xanthate esters, to generate alkyl radicals as the key intermediates. This aryl radical activation approach represents a new strategy for the activation of alcohols as cross-coupling partners.

  鉴于其在天然产物和药物中的普遍存在，醇是构建 C-C 键最有吸引力的起始材料之一。我们在此报告了第一个利用芳基的反应性来激活醇衍生的黄原酸酯中的 C-O 键的催化策略，从而发现了第一个催化脱氧二氟甲基化反应。在铜催化条件下，很容易从醇原料合成的各种烷基黄原酸酯被催化生成的芳基活化，并通过烷基中间体转化为烷基二氟甲烷产物。这种可扩展的协议具有广泛的底物范围和官能团耐受性，能够对复杂的药剂进行后期修饰。已开发出一种一锅法，允许直接使用游离醇而无需纯化黄原酸酯。机理研究与芳基自由基形成并引发黄原酸酯的 C-O 键断裂以产生作为关键中间体的烷基自由基的假设一致。这种芳基自由基活化方法代表了一种将醇作为交叉偶联物活化的新策略。
