From isonitrile to nitrile via ketenimine intermediate: Palladium-catalyzed 1,1-carbocyanation of ally carbonate by alpha-isocyanoacetate

David Savary, Qian Wang, Jieping Zhu, Guanyinsheng Qiu, Sheng-Cai Zheng

A palladium-catalyzed 1,1-carbocyanation of allyl carbonate by alpha-quaternary alpha-isocyanoacetate was developed. Formation of ketenimine followed by homolysis of the C-N bond and recombination of the resulting caged radical pair was proposed to account ...

Ketenimines from Isocyanides and Allyl Carbonates: Palladium-Catalyzed Synthesis of β,γ-Unsaturated Amides and Tetrazoles

Jieping Zhu, Qian Wang, Mathias Mamboury, Guanyinsheng Qiu

The reaction of allyl ethyl carbonates with isocyanides in the presence of a catalytic amount of Pd(OAc)2 provided ketenimines through b-hydride elimination of the allyl imidoylpalladium intermediates. The insertion of the isocyanide into the p-allyl Pd co ...

Palladium-Catalyzed Three-Component Reaction of Propargyl Carbonates, Isocyanides, and Alcohols or Water: Switchable Synthesis of Pyrroles and Its Bicyclic Analogues

Jieping Zhu, Qian Wang, Guanyinsheng Qiu

In the presence of a catalytic amount of Pd(OAc)2 and a stoichiometric amount of tert-butylamine, the reaction of propargyl carbonates, isocyanides, and alcohols afforded polysubstituted aminopyrroles in good yields. Using water as a nucleophile instead of ...
