Short and sweet: Glycosidation of 2-deoxyglycosyl imidates with I2 as shown in the scheme (Bn=benzyl, Bz=benzoyl, MS=molecular sieves) proceeds smoothly to provide the corresponding β-linked 2-deoxyglycosides in excellent yields and selectivity. This coupling method has been shown to be adaptable to the synthesis of various β-linked oligosaccharides containing 2,6-dideoxy- and 2,3,6-trideoxyglycosides.
