N‑Heterocyclic Carbene-Catalyzed Diastereoselective Vinylogous Michael Addition Reaction of γ‑Substituted Deconjugated Butenolides

An efficient N-heterocyclic carbene (NHC)-catalyzed vinylogous Michael addition of deconjugated butenolides was developed. In the presence of 5 mol % of the NHC catalyst, both γ-alkyl- and aryl-substituted deconjugated butenolides undergo vinylogous Michael addition with various α, β-unsaturated ket...
