A new strategy has been developed for the synthesis of C-aryl glycosides based on a xanthate-mediated free radical addition–cyclization sequence of an acetophenone xanthate to a vinylic carbohydrate followed by aromatization.

A simple, highly efficient and cheap synthesis of substitutednaphthalenes is reported. These aromatic compounds can be easily prepared in acidic or basic conditions from [small alpha]-tetralones, obtained by a xanthate-mediated addition-cyclisation sequence.
