4-Cyclo-propyl-1-(6'-de-oxy-1',2'-O-iso-propyl-idene-α-d-gluco-furanos-yl)-1H-1,2,3-triazole.

In the title compound, C14H21N3O5, the tetra-hydro-furan ring adopts an envelope conformation with the C atom bearing the substituent as the flap. The penta-furan-ose ring adopts a twisted conformation about the C-C bond fusing the rings. The dihedral angle between these rings (all atoms), which are cis fused, is 72.89 (14)°. The cyclo-propane ring is disordered over two orientations in a 0.576 (5):0.424 (5) ratio; the dihedral angles subtended to the triazole ring are 53.3 (11) and 46.6 (9)°, respectively. In the crystal, the mol-ecules are linked by O-H⋯N and O-H⋯O hydrogen bonds, generating (001) sheets. A weak C-H⋯O inter-action also occurs.
