A novel self-promoted Morita-Baylis-Hillman-like dimerization
《Chinese Science Bulletin》2010年第25期2794-2798,共5页LI Qiang WongKhan Kittiya LUO XianCai Batsanov Andrei S Howard Judith A K LAN Yu WU YunDong Marder Todd B LEI AiWen 
supported by the National Natural Science Foundation of China (20832003,20772093)
While stable in CH2Cl2, hexane or THF, in the presence of MeOH, self-promoted dimerization of the triarylphosphine-alkene 1, a ligand for Pd-catalyzed reactions, produced an unusual racemic bis(phosphine) 2 in high yi...

Privileged chiral catalysts in asymmetric Morita-Baylis-Hillman/aza-Morita-Baylis-Hillman reaction被引量：1
《Chinese Science Bulletin》2010年第17期1699-1711,共13页WEI Yin SHI Min 
supported by Shanghai Municipal Committee of Science and Technology (06XD14005 and 08dj1400100-2);National Basic Research Program of China (2009CB825300);the National Natural Science Foundation of China (20872162, 20672127, 20821002 and 20732008)
In the past decade, the asymmetric Morita-Baylis-Hillman (MBH)/aza-Morita-Baylis-Hillman (aza-MBH) reaction has attracted great attention because it leads to the formation of densely functionalized products in a catal...

Project supported by the National Natural Science Foundation of China.
A ring R denotes a commutative associative ring with identity and each R-module isunitary. For the concepts and symbols not defined here we refer to refs. [1, 2]. We callR co-Noetherian (V’amos ring) in the case wher...
