Glycosyl azides transformations

Tsukamoto, H, Kondo, Y, 1-Fluoropyridinium triflates versatile reagents for transformation of thioglycoside into O-glycoside, glycosyl azide and sulfoxide. Tetrahedron Lett., 44, 5247-5249, 2003. [Pg.180]

Dipolar cycloaddition of glycosyl azides 245 to 1,4-naphthoquinones has been observed. At room temperature, the l-glycosylnaphtho[2,3-J]triazole-4,9-dione (266) was formed selectively in low yield at elevated temperatures decomposition of the cycloadduct took place and several transformation products of 266 were identified. [Pg.147]

The reaction of glycosyl azides with phosphates has proved less popular, but it was first studied with acetylated pentopyranosyl azides and the products are glycosyl phosphoramidates (glycosyl amidophosphates). Paulsen et demonstrated this transformation with o-manno-heptose derivatives. The oc-azide... [Pg.151]

The foregoing sections have discussed the chemical properties and transformations of glycosyl azides. This section is devoted to the results concerning structural elucidation and conformational studies of glycosyl azides. [Pg.161]
