  钯催化的分子内碳插入C（sp3）-H键

  摘要：

  开发了钯催化的卡宾插入C（sp 3）-H键导致吡咯烷。偶合反应可被Pd 0和Pd II催化，具有区域选择性，并显示出宽泛的官能团耐受性。该反应是从重氮羰基化合物开始的钯催化的C（sp 3）-C（sp 3）键组装的第一个例子。DFT计算表明，这种直接的C（sp 3）-H键官能化反应涉及前所未有的一致的金属化-去质子化步骤。

  Palladium-Catalyzed Intramolecular C−O Bond Formation

  摘要：

  A number of oxygen heterocycles were synthesized using the palladium-catalyzed intramolecular etherification of aryl halides by employing di-tert-butylphosphinobiaryl ligands. The reaction proceeds under mild conditions using weak bases such as Cs2CO3 or K3PO4. A variety of functional groups are tolerated in the reaction. and enantioenriched alcohols can be coupled without erosion of optical purity. The mildness of the reaction conditions allows for the use of polyfunctionalized substrates. This method was used as the key step in the synthesis of MKC-242, an antidepressant currently in clinical trials. The synthesis of MKC-242 was achieved in 40% overall yield from commercially available sesamol and acrylonitrile,

  and medium-sized rings are important in many scientific fields and technologies but are hard to make using current methods, especially on a large scale. Outlined herein is a strategy by which functionalized macrocycles and medium-sized rings can be prepared using cyclization/ring expansion (CRE) cascade reactions, without resorting to high dilution conditions. CRE cascade reactions are designed to operate

  大环和中型环在许多科学领域和技术中都很重要，但使用现有方法很难制造，尤其是大规模制造。本文概述了一种策略，通过该策略可以使用环化/扩环（CRE）级联反应来制备官能化大环和中等大小的环，而不需要采用高稀释条件。 CRE 级联反应专门通过动力学有利的 5-7 元环环化步骤进行操作；这意味着避免了通常与经典的端到端大环化反应相关的问题。已经开发出一种模块化合成方法，以促进所需线性前体的简单组装，然后可以使用九种 CRE 方案之一将其转化为极其广泛的官能化大环化合物和中等大小的环。

  palladium‐catalyzed carbene insertion into C(sp3)−H bonds leading to pyrrolidines was developed. The coupling reaction can be catalyzed by both Pd0 and PdII, is regioselective, and shows a broad functional group tolerance. This reaction is the first example of palladium‐catalyzed C(sp3)−C(sp3) bond assembly starting from diazocarbonyl compounds. DFT calculations revealed that this direct C(sp3)−H bond functionalization
