A highly efficient method to afford 2,3-unsaturated glycosides was described. In the presence of Hafnium(IV) triflate, a variety of 2,3-unsaturated-O- and S-glycosides have been obtained by stereoselective glycosylation of 3,4,6-tri-O-acetyl-d-glucal and hexa-O-acetyl-d-lactal with various acceptors in good isolated yields.

I2 is an effective promoter for the synthesis of 2,3-unsaturated glycosides via Ferrier glycosylation. This reaction was used in the present work for the synthesis of O-glycosylated Fmoc amino acid building blocks. This metal-free reaction affo
