Multicomponent Multicatalyst Reactions (MC)2R: One-Pot Synthesis of 3,4-Dihydroquinolinones


Multicomponent Multicatalyst Reactions (MC)2R: 
One-Pot Synthesis of 3,4-Dihydroquinolinones
Lei Zhang, Lorenzo Sonaglia, Jason Stacey, and Mark Lautens Org. Lett. 2013152128-2131. DOI:10.1021/ol4006008 .

A Rh/Pd/Cu catalyst system led to an efficient synthesis of dihydroquinolinones in one-pot, two operations. The reaction features the first triple metal-catalyzed transformations in one reaction vessel, without any intermediate workup. The conjugate-addition/amidation/amidation reaction sequence is highly modular, divergent, and practical.

Heterogeneous catalytic approaches in C-H activation reactions

Green Chem., 2016, Advance Article
DOI: 10.1039/C6GC00385K, Critical Review

This review summarizes the development of user-friendly, recyclable and easily separable heterogeneous catalysts for C-H activation during the last decade until December 2015.

http://pubs.rsc.org/en/Content/ArticleLanding/2016/GC/C6GC00385K?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+rss%2FGC+%28RSC+-+Green+Chem.+latest+articles%29#!divAbstract

Despite the undisputed advances and progress in metal-catalyzed C–H functionalizations, this atom-economical approach had thus far largely been developed with the aid of various metal catalysts that were operative in a homogeneous fashion. 

While thereby major progress was accomplished, these catalytic systems featured notable disadvantages, such as low catalyst recyclability. This review summarizes the development of user-friendly, recyclable and easily separable heterogeneous catalysts for C–H activation.

This strategy was characterized by a remarkably broad substrate scope, considerable levels of chemo- and site-selectivities and proved applicable to C–C as well as C–heteroatom formation processes. 

Thus, recyclable catalysts were established for arylations, hydroarylations, alkenylations, acylations, nitrogenations, oxygenations, or halogenations, among others. The rapid recent progress in selective heterogeneous C–H functionalizations during the last decade until December 2015 is reviewed.
