Turning constraint into opportunity: development of a four-component Catellani reaction

引用

Science Bulletin 2020年第23期65卷 1961-1963页

Polyfunctional arenes are key structural scaffolds commonly found in natural products, pharmaceuticals, fine chemicals and materials [1]. As such, the development of rapid and efficient methods to functionalize these scaffolds has received substantial attention, leading to the development of several elegant synthetic strategies. Among these methods, the Catellani reaction。

Transfer Hydrogenation of C= C Double Bonds Catalyzed by Ruthenium Amido-Complexes: Scopes, Limitation and Enantioselectivity

引用

有机化学 2004年第Z1期24卷 53-页

作者： XUE,Dong CHENG,Ying-Chun CUI,Xin WANG,Qi-Wei ZHU,Jin DENG,Jin-Gen Key Laboratory of Asymmetric Synthesis & Chirotechnology of Sichuan Province and Union Laboratory of Asymmetric Synthesis Chengdu Institute of Organic Chemistry Chinese Academy of Sciences Chengdu 610041

The reduction of C = C double bonds is one of the most fundamental synthetic transformations and plays a key role in the manufacturing of a wide variety of bulk and fine chemicals. Hydrogenation of olefinic substrates can be achieved readily with molecular hydrogen in many cases, but transfer hydrogenation methods using suitable donor molecules such as formic acid or alcohols are receiving increasing attention as possible synthetic alternatives because it requires no special equipment and avoids the handling of potentially hazardous gaseous hydrogen.……
