  NHC促进立体异构和化学扩散的芳烷基烯酮与氯的官能化

  摘要：

  用N-杂环卡宾处理烷基芳基烯酮和三氯乙醛（氯代）时，观察到立体和化学发散对映选择性反应途径，选择性地产生β-内酯（高达88:12 dr，高达94％  ee）或α-氯代酯（高达至94％  ee）。乙烯酮中的2-芳基取代或α-支链的i Pr烷基取代基都有利于氯化途径，从而使氯醛可以在不对称催化中用作亲电子氯化试剂。

  photoinduced copper‐catalyzed asymmetric radical decarboxylative alkynylation of bench‐stable N‐hydroxyphthalimide(NHP)‐type esters of racemic alkyl carboxylic acids with terminal alkynes, which provides a flexible platform for the construction of chiral C(sp3)−C(sp) bonds. Critical to the success of this process are not only the use of the copper catalyst as a dual photo‐ and cross‐coupling catalyst but

  我们描述了外消旋烷基羧酸的N-羟基邻苯二甲酰亚胺（NHP）型酯与末端炔烃的光诱导铜催化不对称自由基脱羧烷基化反应，为手性C的构建提供了灵活的平台（sp 3）-C（sp）键。该方法成功的关键不仅在于将铜催化剂用作光和交联的双重催化剂，而且还需要调整NHP型酯以分别抑制烷基和末端炔烃的均质二聚化。由于使用了稳定且易于获得的NHP型酯，与使用烷基卤化物对应物的反应相比，该反应的底物范围更广，涵盖了（杂）苄基，烯丙基和氨基羰基取代的羧酸衍生物，并且（杂芳基和烷基以及甲硅烷基炔烃，因此为先前报道的方法提供了至关重要的补充方法。

  for the long-standing challenge of conducting the palladium-catalyzed α-arylation of carboxylic aids and secondary amides with aryl halides. Both of the presented coupling processes occur with a variety of carboxylic acids and amides and with a variety of aryl bromides containing a broad range of functional groups, including base-sensitive functionality like acyl, alkoxycarbonyl, nitro, cyano, and even

  针对钯催化羧酸助剂和仲酰胺与芳基卤化物的 α-芳基化这一长期存在的挑战，提出了一种新颖的无痕保护策略。所提出的两种偶联过程均与各种羧酸和酰胺以及各种含有多种官能团的芳基溴发生，包括碱敏感官能团，如酰基、烷氧基羰基、硝基、氰基，甚至羟基。通过该方法一步制备了5种商品化药物，收率81-96%。低钯负载量药物萘普生和氟比洛芬的克级合成进一步凸显了该方法的实用价值。
• Highly Enantioselective Direct Alkylation of Arylacetic Acids with Chiral Lithium Amides as Traceless Auxiliaries
  作者：Craig E. Stivala、Armen Zakarian

  DOI：10.1021/ja205107x

  日期：2011.8.10

  A direct, highly enantioselective alkylation of arylacetic acids via enediolates using a readily available chiral lithium amide as a stereodirecting reagent has been developed. This approach circumvents the traditional attachment and removal of chiral auxiliaries used currently for this type of transformation. The protocol is operationally simple, and the chiral reagent is readily recoverable.
