7-Cyclo­propyl-2′-de­oxy­tubercidin: a carbocyclic side-chain derivative of 7-de­aza-2′-de­oxy­adenosine

7-Cyclo­propyl-2′-de­oxy­tubercidin, a carbocyclic side-chain derivative of 7-de­aza-2′-de­oxy­adenosine, exhibits an anti glycosylic bond conformation.The furan­ose group shows a twisted C1′-exo sugar pucker (S-type), the orientation of the exocyclic C4′—C5′ bond is -ap (trans) and the cyclo­propyl substituent points away from the nucleobase (anti orientation). Within the three-dimensional extended crystal structure, the individual mol­ecules are stacked and arranged into layers, which are highly ordered and stabilized by hydrogen bonding.
