A comparative analysis of mono- and disaccharide benzyl fucopyranosides

M. Brito-Arias, E. Durán-Páramo, I. Mata and E. Molins

Abstract: The syntheses and X-ray analyses of two fucopyranosides, the monosaccharide benzyl 3,4-di-O-acetyl-2-hydroxy- [beta] -D-fucopyranoside, C₁₇H₂₂O₇, and the disaccharide 1-benzyl O-(2,3-di-O-acetyl-4,6-O-benzylidene- [beta] -D-glucopyranosyl)-(1 $\rightarrow$ 2)-3,4-O-isopropylidene- [beta] -D-fucopyranoside, C₃₃H₄₀O₁₂, are described. The different substituents induce small conformational changes on the fucopyranoside ring. However, the conformation of the benzyl group varies from (+)gauche for the monosaccharide to synperiplanar for the disaccharide.

Formula: C₁₇H₂₂O₇ and C₃₃H₄₀O₁₂
