4-Cyclo­propyl-1-(6′-de­oxy-1′,2′-O-iso­propyl­idene-α-D-gluco­furanos­yl)-1H-1,2,3-triazole

In the title compound, C₁₄H₂₁N₃O₅, the tetra­hydro­furan ring adopts an envelope conformation with the C atom bearing the substituent as the flap. The penta­furan­ose 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 cyclo­propane 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 mol­ecules are linked by O—H...N and O—H...O hydrogen bonds, generating (001) sheets. A weak C—H...O inter­action also occurs.

1,2:1′,2′-Di-O-iso­propyl­idenedi­furan­ose-C12 higher carbon sugar

In the title compound, C₁₈H₂₈O₈, the five-membered ring with one O atom attached to the ethyl substituent has a twisted conformation about the C—O bond. The adjacent cis-fused ring with two O atoms also has a twisted conformation about one of the C—O bonds. The dihedral angle between these rings (all atoms) is 59.05 (12)°. The five-membered ring linked to the ethynyl susbtituent is twisted about a C—C bond; the cis-fused adjacent ring is twisted about a C—O bond [dihedral angle between the rings (all atoms) = 71.78 (12)°]. Two intra­molecular O—H...O hydrogen bonds occur. In the crystal, mol­ecules are linked by O—H...O hydrogen bonds, generating [001] chains.
