cation activation strategy for dehydrative glycosylation reactions employing the readily available and economical geminal dichloroimidazolidinediones (DCIDs) that promotes the glycosylation between 2-deoxy- and 2,6-dideoxy-sugar hemiacetals with various acceptors in good yields and high α-selectivity. This research not only provides a mild and efficient alternative approach for stereoselective dehydrative
