  Highly Enantioselective Azadiene Diels−Alder Reactions Catalyzed by Chiral N-Heterocyclic Carbenes

  摘要：

  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 enolate dienophiles that undergo LUMOdiene-controlled Diels-Alder reactions with N-sulfonyl-alpha,beta-unsaturated imines in good yields and with exceptional diastereo- and enantioselectivities (>99% ee). In contrast to uncatalyzed variants, this organocatalytic process proceeds at room temperature without stoichiometric reagents, producing synthetically valuable, enantiomerically pure cis-3,4-disubstituted dihydropyridinone products.

  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, it produces the desired compounds without the concomitant production of a large volume of metallic waste. Chiral heterocyclic carbene catalysts of the invention and methods of using these catalysts produce chiral heterocycles in high enantiomeric and diastereomeric excess.
