Homogeneous azidophenylselenylation of glucals

The homogeneous azidophenylselenylation of diversely protected mono-, di- and trisaccharide glucals was studied to evaluate the influence of protective groups, N3 and I donors, temperature and solvent on the stereoselectivity of the formation of corresponding phenyl 2-azido-2-deoxy-1-seleno-α-D-gluco- and -manno-adducts.

Preparation of diversely protected 2-azido-2-deoxyglycopyranoses from glycals

A new and efficient preparation of diversely protected 2-azido-2-deoxyglycopyranosides from the corresponding glycals is described. The glycals are first transformed into protected phenyl 2-azido-2-deoxy-selenoglycopyranosides by azido-phenylselenylation.

New and Efficient Synthesis of Protected 2-Azido-2-deoxy-glycopyranoses from the Corresponding Glycal

Diversely protected 2-azido-2-deoxy-D-glycopyranoses are prepared by azido phenylselenylation of the corresponding glycal followed by hydrolysis of the resulting selenoglycosides: from protected D-galactal, protected 2-azido-2-deoxy-D-galactopyranose is obtained, as the sole product in 72percent overall yield.
