Stereoselective N-Heterocyclic-Carbene-Catalyzed Formal [4+2] Cycloaddition: Access to Chiral Heterocyclic Cyclohexenones
The present study reports an asymmetric NHC-catalyzed formal [4 + 2] cycloaddition of heterocyclic alkenes containing a polarized double bond with an azolium-dienolate intermediate generated from α-bromo-α,β-unsaturated aldehydes without external oxi...
