- Description
- Short syntheses to high Fsp3 index natural-product analogues such as iminosugars are of paramount importance in the investigation of their biological activities and reducing the use of protecting groups is an advantageous synthetic strategy. An isopropylidene group was employed towards the synthesis of seven-membered ring iminosugars and the title compound, C9H15N3O5, was crystallized as an intermediate, in which the THF ring is twisted and the dioxolane ring adopts an envelope conformation: the dihedral angle between the rings is 67.50 (13)°. In the crystal, the hydroxyl groups participate in O—H...(O,O) and O—H...N hydrogen-bonding interactions, which generate chains of molecules propagating parallel to the a-axis direction. There is a notable non-classical C—H...O hydrogen bond, which cross-links the [100] chains into (001) sheets.
