  Lewis Acid Activation of Carbodicarbene Catalysts for Rh-Catalyzed Hydroarylation of Dienes

  摘要：

  The activation of carbodicarbene (CDC)-Rh(I) pincer complexes by secondary binding of metal salts is reported for the catalytic site-selective hydro-heteroarylation of dienes (up to 98% yield and >98:2 gamma:alpha). Reactions are promoted by 5 mol % of a readily available tridentate (CDC)-Rh complex in the presence of an inexpensive lithium salt. The reaction is compatible with a variety of terminal and internal dienes and tolerant of ester, alkyl halide, and boronate ester functional groups. X-ray data and mechanistic experiments provide support for the role of the metal salts on catalyst activation and shed light on the reaction mechanism. The increased efficiency (120 to 22 degrees C) made available by catalytic amounts of metal salts to catalysts containing C(0) donors is a significant aspect of the disclosed studies.

  作者：Ryosuke Matsubara、Timothy F. Jamison

  DOI：10.1002/asia.201000875

  日期：2011.7.4

  This report describes a nickel‐catalyzed allylic substitution process of simple alkenes whereby an important structural motif, a 1,4‐diene, was prepared. The key to success is the use of an appropriate nickel–phosphine complex and a stoichiometric amount of silyl triflate. Reactions of 1‐alkyl‐substituted alkenes consistently provided 1,1‐disubstituted alkenes with high selectivity. Insight into the

  该报告描述了镍催化简单烯烃的烯丙基取代过程，由此制备了重要的结构基序，即 1,4-二烯。成功的关键是使用适当的镍-膦络合物和化学计量的三氟甲磺酸硅酯。1-烷基取代的烯烃的反应始终以高选择性提供 1,1-二取代的烯烃。还记录了对反应机制的深入了解以及所开发的催化过程的各种应用。

  widespread use in pharmaceutical chemistry. In particular, chiral allylic sulfones have drawn particular interest because of their synthetic utility. However, enantioselective synthesis of 1,3-disubstituted unsymmetrical chiral allylic sulfones remains a challenge. In this article, we report a protocol for (R)-DTBM-Segphos/Pd-catalyzed regio- and enantioselective hydrosulfonylation of 1,3-dienes with sulfinic

  由于其在药物化学中的广泛应用，手性砜是有机合成中的重要结构基序。特别是，手性烯丙基砜因其合成效用而引起了特别的兴趣。然而，1,3-二取代的不对称手性烯丙基砜的对映选择性合成仍然是一个挑战。在本文中，我们报告了 (R)-DTBM-Segphos/Pd 催化的 1,3-二烯与亚磺酸的区域选择性和对映选择性氢磺酰化的方案，该方案提供了原子和步骤经济的 1,3-二取代手性烯丙基砜。反应条件温和，底物范围广。结合实验和计算研究表明，反应是由配体到配体的氢转移引发的，然后是通过六元过渡态的 CS 键还原消除。发现底物的烯烃 CH 与 (R)-DTBM-Segphos 的叔丁基之间的空间排斥是对映控制的关键因素。
