Abstract
A series of novel diphenyl ethylenediamine (DPEN) derived C2 symmetric dihydroimidazolium cyclophanes were designed and synthesized as organo NHC precatalysts. The resultant organo NHC-catalyzed reactions with superior enantioselectivity than traditional C2 dihydroimidazolidine NHCs as exemplified by NHC-catalyzed asymmetric intramolecular Stetter reactions.
