The furanose ring A adopts a oT4 conformation. The fused dioxolane ring B and the substituent dioxolane ring C also have twisted conformations. There are no strong hydrogen bonds in the crystal structure: only weak CHO contacts are present, which link the molecules to form a three-dimensional...

This compound is a derivative of xylofuranose, a five-membered ring sugar molecule. The presence of two isopropylidene groups at positions 1 and 2, and positions 3 and 5, respectively, gives this compound its unique structure. It is commonly used as a protecting group for the hydroxyl groups...
Synthesis and Structure of 1-D-6-O-(2-Amino-2-deoxy-α- and -β-D-gluco- and -galactopyranosyl)-3-O-methyl-D-chiro-inositol A convenient preparative synthesis of 1-D-6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-3-O-methyl-chiro-inositol (Ia), 1D-6-O-(2-amino-2-deoxy-β-D-gl...
with this structure, the HO–C–C–OH dihedral angle is sufficiently small to allow the formation of a planar five-membered ring18. The silicate or borate scenarios have shown the high potential of inorganic/organic interactions, although the presence of significant borate on the early Earth is...
To investigate the substituent effects at the 3-O and 6-O positions on ring-opening polymerization, 3,6-di-O-benzyl-α-d-glucopyranose 1,2,4-orthopivalate ... Hiroshi,Kamitakahara,Michiko,... - 《Macromolecules》 被引量: 63发表: 1996年 Structure of the K2 capsule associated with the KL...
The three-dimensional arrangement of the constituent atoms of the ring structure of mono saccharides is more readily visualized when the structure is depicted in the Haworth projection (after W. H. Haworth) (Fig. 5-5). In this projection, the members of the ring are arranged in a p...
