摘要：

2,3-Unsaturated C-glycosides were obtained in good to excellent yields from the trimethylsilyltriflate catalyzed reaction between carbohydrate derived cyclic enolethers (,,glycals'') and trimethylsily] ketene acetals; under similar conditions vinylogous lactones afforded the products of an 1,4-addition reaction.
