Strain-driven palladium/N-heterocyclic carbene-catalyzed C-C bond activation of diphenylcyclopropenone (DPC) was explored for one-step access to trisubstituted α,β-unsaturated esters and amides. The designed transformation worked under mild conditions providing exclusively a single stereoisomer. Mechanistic studies support the oxidative addition of the C-C bond of cyclopropenone to in-situ-generated Pd(0) intermediate. Vinylic hydrogen in the product was proved that it is coming from phenol/aniline through deuterium-labeling studies. Late-stage functionalization of bioactive mols. such as procaine, estrone, and hymecromone demonstrated the robustness of this protocol.
