with regioselectivity. An alternative approach is to use ubiquitous carboxylic acids as starting materials and perform a decarboxylative coupling. Herein, we report conditions for a photocatalytic decarboxylative C-O bond formation reaction that provides rapid and facile access to the corresponding acetoxylated products. Mechanistic investigations suggest that the reaction operates via oxidation of the
The Pummererreaction of acyclic sulfoxides with O-silylated ketene acetal has been shown to proceed with high diastereoselective deprotonation of the α-methylene proton. A plausible reaction mechanism involving the anti elimination process is proposed from deuterium-labeling experiment.
