7-(2'-Deoxy-α-D-ribofuranosyl)hypoxanthine

The α-configured N7 analogue of 2′-deoxyinosine [7-(2′-deoxy-α-D-ribofuranosyl)hypoxanthine, C₁₀H₁₂N₄O₄] shows the following structural characteristics: (i) the furanose part of the molecule adopts the 2′-endo conformation [pseudorotation phase angle 166.4 (2)°]; (ii) the torsion angle χ (O4′—C1′—N7—C5) is syn [70.9 (1)°] with the base substituent pointing away from the sugar unit; (iii) the nucleobases are not hydrogen bonded to each other; only sugar-base hydrogen bonds between adjacent molecules were detected.
