Synthesis of indoles via palladium-catalyzed C–H activation of N-aryl amides followed by coupling with alkynes
摘要:
A convenient and efficient method for the construction of indole skeleton was developed via Pd-catalyzed C-H activation of N-aryl amides and subsequent coupling with alkynes. Both stoichiometric and catalytic versions have been successfully achieved. (C) 2011 Elsevier Ltd. All rights reserved.

traditional small molecule drug design and are often referred to as “undruggable”. The 20Sproteasome is the main protease that targets IDPs for degradation and therefore small molecule 20Sproteasome enhancement presents a novel therapeutic strategy by which these undruggable IDPs could be targeted. The concept of 20S activation is still relatively new, with few potent activators having been identified

A simple, sustainable, efficient, mild, and low‐cost protocol was developed for d‐glucose‐assisted Cu‐catalyzed Ullmann reactions in water for amides, carbamates, and nitrogen‐containing heterocycles. The reaction was compatible with diverse aryl/heteroaryl iodides, giving highly substituted pyridine, indole, or indazole rings. This method offers an attractive alternative to existing protocols, because

The preparation of secondary 2,2′-bisanilides has been successfully achieved through an oxidative coupling of aryl ortho-sp2 C–H bonds of anilides in the presence of catalytic Pd(OAc)2 and K2S2O8 as an oxidant in MsOH/CF3CO2H (TFA) at roomtemperature (25 °C). The aromatic rings of anilides substituted by various electron-donating or electron-withdrawing groups are tolerant in these coupling reactions
通过在催化性Pd(OAc)2和K 2 S 2 O 8作为氧化剂的存在下,通过对苯甲酸酯的芳基邻-sp 2 C-H键进行氧化偶联,成功地完成了2,2'-双苯胺的制备。在室温(25°C)下在MsOH / CF 3 CO 2 H(TFA)中溶解。在这些偶联反应中,被各种给电子或吸电子基团取代的苯甲酸酯的芳环是可容忍的。
