Rhodium catalyzed enantioselective cyclization of substituted imidazoles via C-H bond activation.

Andy S Tsai1, Rebecca M Wilson, Hitoshi Harada, Robert G Bergman, Jonathan A Ellman.   

Abstract

The enantioselective intramolecular alkylation of substituted imidazoles with enantiomeric excesses up to 98% has been accomplished by rhodium catalyzed C-H bond functionalization with (S,S',R,R')TangPhos as the chiral ligand.
