  摘要：

  报道了通过烯烃氯官能化进行动力学拆分的第一个例子。发现外消旋不饱和酰胺的对映异构体在多种溶剂中对手性路易斯碱具有不同的氢键亲合力。这种相互作用被用于通过卤环化开发外消旋不饱和酰胺的动力学拆分。相同的催化剂既可以在基材中“感知手性”，又可以将高度选择性的氯传递到烯烃官能团上，从而产生高达 99:1 dr 和高达 98.5:1.5 er 的立体三元组产物。选择性因子通常大于 50，以允许以接近 50% 的产率同时合成高度对映体富集形式的产物和未反应的底物。该反应使用催化量（≤0.

  A Lewis-acid-catalyzed method for the substrate-directed formation of peptide bonds has been developed, and this powerful approach is utilized for the new "remote" activation of carboxyl groups under solvent-free conditions. The presented method has the following advantages: 1) the high-yielding peptide synthesis uses a tantalum catalyst for any amino acids; 2) the reaction proceeds without any racemization;

  一种路易斯酸催化的底物定向形成肽键的方法已经被开发出来，这种强大的方法被用于在无溶剂条件下对羧基进行新的“远程”活化。该方法具有以下优点：1）高产肽合成对任何氨基酸均使用钽催化剂；2) 反应进行时没有任何外消旋化；3）采用钛催化剂的新型底物导向化学连接适用于会聚肽合成。这些优势克服了经典肽合成中一些未解决的问题。

  日期：2008.7

  Oxidative amidation of aldehydes and alcohols with amines to afford the corresponding amides in excellent yields and ee values over 98 % is achieved by using a catalytic amount of KI in combination with TBHP as the external oxidant. This method avoids the use of expensive and/or air-sensitive reagents. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

  Herein, we report a one‐electron strategy for catalytic amide synthesis that enables the direct carbamoylation of (hetero)aryl bromides. This radical cross‐coupling approach, which is based on the combination of nickel and photoredox catalysis, proceeds at ambient temperature and uses readily available dihydropyridines as precursors of carbamoyl radicals. The method's mild reaction conditions make

  在本文中，我们报告了一种催化酰胺合成的单电子策略，该策略可实现（杂）芳基溴化物的直接氨基甲酰基化。这种自由基交叉偶联方法基于镍和光氧化还原催化的结合，在环境温度下进行，并使用现成的二氢吡啶作为氨基甲酰基自由基的前体。该方法温和的反应条件使其能够耐受敏感的官能团底物，并允许在生物学相关的杂环中安装酰胺支架。此外，我们安装了带有电子贫乏和空间受阻胺部分的酰胺官能团，而这是用传统的脱水缩合方法难以制备的。
