Controllable Diastereoselective Cyclopropanation. Enantioselective Synthesis of Vinylcyclopropanes via Chiral Telluronium Ylides
Liao, Wei-Wei,Li, Kai,Tang, Yong
, p. 13030 - 13031 (2003)
Novel chiral telluronium salts 1 are designed for asymmetric synthesis of 1,3-disubstituted 2-vinylcyclopropanes. The allylides, generated in situ from the corresponding telluronium salt in the presence of different base, reacted with α,β-unsaturated este
Enantioselective synthesis of vinylcyclopropanes and vinylepoxides mediated by camphor-derived sulfur ylides: Rationale of enantioselectivity, scope, and limitation
Deng, Xian-Ming,Cai, Ping,Ye, Song,Sun, Xiu-Li,Liao, Wei-Wei,Li, Kai,Tang, Yong,Wu, Yun-Dong,Dai, Li-Xin
, p. 9730 - 9740 (2007/10/03)
By a sidearm approach, camphor-derived sulfur ylides 1 were designed and synthesized for the cyclopropanation of electron-deficient alkenes and epoxidation of aldehydes. Under the optimal conditions, the exo-type sulfonium salts 4a and 4b reacted with β-a
A novel chiral sulfonium yilde: Highly enantioselective synthesis of vinylcyclopropanes
Ye, Song,Huang, Zheng-Zheng,Xia, Chun-An,Tang, Yong,Dai, Li-Xin
, p. 2432 - 2433 (2007/10/03)
A newly designed chiral sulfonium allylide, generated in situ from the corresponding sulfonium salt in the presence of KOBut, reacted with α,β-unsaturated esters, ketones, amides, and nitriles to afford trans-2-silylvinyl-trans-3-substituted cy
