1,2:1',2'-Di-O-iso-propyl-idenedi-furan-ose-C12 higher carbon sugar.

ABSTRACT: 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 intra-molecular O-H?O hydrogen bonds occur. In the crystal, mol-ecules are linked by O-H?O hydrogen bonds, generating [001] chains.

Project description:The title compound, C(10)H(15)NO(7), consists of one methyl-enedi-oxy ring and two fused tetra-hydro-furan rings. The three fused rings exhibit cis arrangements at the ring junctions.

Crystal structure of 6-azido-6-de-oxy-1,2-O-iso-propyl-idene-α-d-gluco-furan-ose.

Project description:Short syntheses to high Fsp 3 index natural-product analogues such as imino-sugars are of paramount importance in the investigation of their biological activities and reducing the use of protecting groups is an advantageous synthetic strategy. An iso-propyl-idene group was employed towards the synthesis of seven-membered ring imino-sugars and the title compound, C9H15N3O5, was crystallized as an inter-mediate, 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 inter-actions, which generate chains of mol-ecules 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.

The absolute structures of the mol-ecules in the crystals of both compounds were confirmed by resonant scattering. In the crystal of 3, neighbouring mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along the b-axis direction. The chains are linked by C-H⋯π inter-actions, forming layers parallel to the ab plane. In the crystal of 4, mol-ecules are also linked by C-H⋯O hydrogen bonds, forming this time helices along the a-axis direction. The helices are linked by a number of C-H⋯π inter-actions, forming a supra-molecular framework.
