Highly enantioselective azadiene diels-alder reactions catalyzed by chiral N-heterocyclic carbenes
Highly enantioselective, N-heterocyclic carbene (NHC)-catalyzed aza-Diels-Alder reactions are described. A novel chiral triazolium salt based on the cis-1,2-aminoindanol platform serves as an efficient precatalyst for the NHC-catalyzed redox generation of
ENANTIOSELECTVE REACTIONS CATALYZED BY CHIRAL TRIAZOLIUM SALTS
This invention provides a convenient method for converting imines and other electrophiles into heterocyclic ring systems. The process does not require the use of metallic reagents, and is catalyzed by an organic heterocyclic carbene catalyst. Accordingly,
