This paper introduces the development of new chiral bicyclo[2.2.1]heptadiene ligands for Rh-catalyzed asymmetric additions of various organoboron reagents to imine derivatives, leading to the formation of enantioenriched alpha-chiral amines. The transformation of the adducts into known natural products or molecules of pharmaceutical importance confirms the synthetic usefulness of this method.
The development of efficient synthetic methods for accessing enantioenriched alpha-chiral amines is of great importance in the disciplines of medicinal and synthetic organic chemistry. Enantioselective Rh-catalyzed 1,2-addition reactions to activated imine derivatives are regarded as useful protocols for forming alpha-chiral amines. This personal account outlines our efforts to develop chiral bicyclo[2.2.1]heptadiene ligands for Rh-catalyzed asymmetric additions of various organoboron reagents to a wide range of imine derivatives. Transformations of the thus-obtained adducts into known natural products or molecules of pharmaceutical importance serve to confirm their synthetic usefulness.
