(Thiolan-2-yl)diphenylmethyl benzyl ether/N,N′-diarylurea cocatalyzed asymmetric aziridination of cinnamyl bromide and aryl aldimine
Wang, Shang-Hua,Chein, Rong-Jie
, p. 2607 - 2615 (2016/05/11)
A dual catalyst system using THT-based chiral sulfide 2a and H-bond donor 10a was developed for the asymmetric imino Corey-Chaykovsky reaction. Under the optimum reaction conditions, cinnamyl bromide reacted with a wide scope of N-diphenylphosphinic aldim
Enantioselective synthesis of diaryl aziridines using tetrahydrothiophene- based chiral sulfides as organocatalysts
Huang, Meng-Ting,Wu, Hsin-Yi,Chein, Rong-Jie
, p. 1101 - 1103 (2014/01/17)
This work describes catalytic and asymmetric aziridinations (15 examples, 95-98% ee) of benzyl bromide and imines via the imino Corey-Chaykovsky reaction using (thiolan-2-yl)diarylmethanol benzyl ether as an organocatalyst. The catalyst and analogues thereof were prepared through an expeditious and efficient synthetic route featuring a double nucleophilic substitution and Shi epoxidation as key steps.
Enantioselective synthesis of (thiolan-2-yl)diphenylmethanol and its application in asymmetric, catalytic sulfur ylide-mediated epoxidation
Wu, Hsin-Yi,Chang, Chih-Wei,Chein, Rong-Jie
, p. 5788 - 5793 (2013/07/25)
This work describes an expeditious and efficient preparation of enantiopure (thiolan-2-yl)diphenylmethanol (2) featuring a double nucleophilic substitution and Shi epoxidation as key steps. One of the applications of its benzyl ether derivative to asymmetric sulfur ylide-mediated epoxidation with up to 92% ee (14 examples) was also demonstrated herein.
