2,6-Dichloro-9-(2′,3′,5′-tri-O-acetyl-β-d-ribofuranosyl)-9H-purine
Abstract
The title synthetic analog of purine nucleosides, C16H16Cl2N4O7, has its acetylated β-furanose ring in a 3′β-envelope conformation, with the corresponding C atom deviating by 0.602 (5) Å from the rest of the ring. The planar part of the furanose ring forms a dihedral angle of 65.0 (1)° with the mean plane of the purine bicycle. In the crystal, molecules form a three-dimensional network through multiple C—H...O and C—H...N hydrogen bonds and C—H...π interactions.
