Enantioselective Diels–Alder reactions of enals and alkylidene diketones catalyzed by N-heterocyclic carbenes
An electron-withdrawing group was introduced to the α-position of chalcones, and the resulting alkylidene diketones showed new reactivities with enals under the catalysis of N-heterocyclic carbenes (NHCs). Selective activation of enals affords enolate equivalents that undergo highly enantioselective...
