  α，β-不饱和羧酸生物催化还原为烯丙基醇

  摘要：

  我们已经开发了强大的体内和体外生物催化系统，能够将α，β-不饱和羧酸还原为烯丙基醇及其饱和类似物。这些化合物是许多工业化学品和制药中的普遍支架。对羧酸还原酶（CAR）的底物谱研究研究未开发的底物空间，例如苯并稠合的（杂）芳族羧酸和α，β-不饱和羧酸，揭示了广泛的底物耐受性，并提供了有关这些底物的反应模式的信息基材。大肠杆菌表达异源CAR的细胞被用作多步氢化催化剂，以将多种α，β-不饱和羧酸转化为相应的饱和伯醇，转化率高达99％以上。大肠杆菌内源性乙醇脱氢酶（ADH）的广泛底物范围以及大肠杆菌细胞出乎意料的C C键还原活性支持了这一点。另外，重组的大肠杆菌细胞将各种苯并稠合的（杂）芳族羧酸转化为相应的伯醇。另一种单罐体外由CAR和葡萄糖脱氢酶（GDH）组成的两酶系统显示了GDH对各种不饱和醛的混杂羰基还原酶活性。因此，将CAR与GDH驱动的NADP（H）回收系统耦合，可从母体羧酸盐中获得多种

• Aryl Radical Activation of C–O Bonds: Copper-Catalyzed Deoxygenative Difluoromethylation of Alcohols

  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。

This deoxygenative cyclization is extensible to a tandem intramolecular cyclization/nucleophilic addition cascade, giving polycyclic carbo- or oxacyclic compounds with controlled stereochemistry. This new gold catalysis is applied to a short synthesis of natural compounds of the brazilane family, including brazilane, O-trimethyl-
