Crystal structures of ethyl 3-azido-2,3-dideoxy-d-arabino-hexopyranoside anomers Original Research Article

The structures of the title α (1) and β (2) anomers of ethyl 3-azido-2,3-dideoxy-d-arabino-exopyranoside (C8H15N3O4) are reported. The single-crystal structures of C8H15N3O4 were determined by X-ray crystallography at 293 K. It has been found that both title compounds crystallize in the orthorhombic space group. In both cases, the unit cell contains four asymmetric molecules. From intensity measurements, it has been shown that each of these molecules adopts a 4C1 chair conformation. The packing arrangement in the unit cell displays a stratified structure. Moreover, medium strength O–H⋯O hydrogen bonds in both crystal lattices can be observed.
