Abstract
Palladium acetate catalyzed C-glycosidation of peracetylated glycals with arylboronic acids in acetonitrile (CH3CN) yields the desired 1-substituted 2,3-unsaturated glycal as well as a byproduct corresponding to the ring-opened pyran, present in varying proportions depending on the reaction conditions used. The byproduct is not formed when toluene/EtOH is used as reaction solvent.
