Crystal structure of 3-O-benzyl-4(R)-C-(1-benzyl-1H-123-triazol-4-yl)-12-O-iso­propyl­idene-α-d-erythro­furan­ose

摘要

The title compound, C23H25N3O4, {systematic name: 1-benzyl-4-[(3aR,5R,6R,6aR)-6-benz­yloxy-2,2-di­methyl­tetra­hydro­furo[2,3-d][1,3]dioxol-5-yl]-1H-1,2,3-triazole}, consists of a substituted 2,2-di­methyl­tetra­hydro­furo[2,3-d][1,3]dioxole. The furan­ose ring adopts an envelope conformation close to C 3-exo, where the C atom substituted by the benz­yloxy group is the flap. The fused dioxolane ring also adopts an envelope conformation, with the methyl­ene C atom as the flap. In the crystal, mol­ecules are linked by weak C—H⋯O hydrogen bonds, forming zigzag chains along [010].
