摘要：

A novel visible-light-induced palladium-catalyzed Heck reaction for bromine sugars and aryl olefins with high regioand stereochemistry selectivity for the preparation of C-glycosyl styrene is described. This reaction takes place in one step at room temperature by using a simple and readily available starting material. This protocol can be scaled up to a wide range of glycosyl bromide donors and aryl olefin substrates. Mechanistic studies indicate that a radical addition pathway is involved.
