Allyl C-Glycosidation of Glycals Mediated by 2,3-Dichloro-5,6-dicyano- p-benzoquinone (DDQ).

TLDR: In this article, a novel and highly stereoselective method for the synthesis of allyl C-glycosides bearing C2-C3 unsaturation has been developed using glycal acetate, allyltrimethylsilane and 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) as a neutral activator.
