Mechanistic Investigations of the Pd-Catalyzed Hydrogenolysis of Ketene Heterodimer β-Lactones

Catalytic hydrogenolysis of the Z-isomer of a series of aryl-substituted ketene heterodimer β-lactones facilitated access to deoxypropionate derivatives with a dr ranging from 54:46 to 86:14, favoring the anti-isomer, and with excellent transfer of chiral

A photoinduced Wolff rearrangement/Pd-catalyzed [3+2] cycloaddition sequence: An unexpected route to tetrahydrofurans

A novel sequential reaction that combines a visible light-induced Wolff rearrangement of α-diazoketones and a Pd-catalyzed [3+2] cycloaddition of vinyl cyclopropanes with the resulting ketenes is described in this work. Selective O-allylic alkylation was observed over C-allylic alkylation, which unexpectedly led to a series of highly functionalized tetrahydrofurans with high efficiency (20 examples, 58-99% yields).

Enantioselective [4+2] cycloaddition of ketenes and 9,10-phenanthrenequinone catalyzed by N-heterocyclic carbenes

Chiral N-heterocyclic carbenes were found to be efficient catalysts for the formal [4+2] cycloaddition reaction of alkyl(aryl)ketenes and 9,10-phenanthrenequinone to give the corresponding cycloadducts in good yields with high enantioselectivities.
