Asymmetric Addition of Aryl Boron Reagents to Enones with Rhodium Dicyclophane Imidazolium Carbene Catalysis

Abstract

Chiral N-heterocyclic carbene ligands based on [2.2]paracyclophanes form complexes with rhodium. These catalysts can be used in the high-yielding and enantioselective asymmetric conjugate addition of arylboron compounds to cyclic and acyclic enones (see scheme).
