Spiro bis-C,C-α-arylglycosides were synthesized in three steps in 78-85% overall yields starting from exo-glycals. The initial Heck type C-aryl addition of exo-glycals with arylboronic acids afforded α-aryl-β-substituted C-glycosides with exclusiv

α-2,3-Unsaturated galactosides were synthesized in good to excellent yields by the initial activation of d-galactals with diethyl phosphorochloridite and the subsequent glycosyl addition via Ferrier rearrangement with various O-nucleophiles in the p

Glycosides play an important rule in an organism, and it is very important to develop the methods to synthesis them. Among them, the O-glycosylation and C-arylglycosylation products display diverse biological activities, such as anti-timor,
