Calculate Digit Verification of CAS Registry Number 1304756-01:
(9*1)+(8*3)+(7*0)+(6*4)+(5*7)+(4*5)+(3*6)+(2*0)+(1*1)=131

Enantioselective bromoaminocyclization using amino-thiocarbamate catalysts

Zhou, Ling,Chen, Jie,Tan, Chong Kiat,Yeung, Ying-Yeung

, p. 9164 - 9167 (2011/08/04)

A facile and efficient enantioselective bromoaminocyclization of unsaturated sulfonamides has been developed using an amino-thiocarbamate catalyst. A range of enantioenriched pyrrolidines were prepared with up to 99% yield and 99% ee. The corresponding lactams could be obtained through oxidation of the pyrrolidines.
