1,7-Dideaza-2'-deoxy-6-nitro­nebularine: a pyrrolo­[2,3-b]pyridine nucleoside with an intra­molecular hydrogen bond stabilizing the syn conformation

H. Yang, S. Budow, H. Eickmeier, H. Reuter and F. Seela

Synopsis: In the title nucleoside, the N-glycosylic bond exhibits a syn conformation and the pento­furanosyl residue adopts a C2'-endo envelope conformation. The orientation of the exocyclic C4'-C5' bond is +sc (gauche, gauche). The nucleoside forms an ordered and stacked three-dimensional network.

Formula: C12H13N3O5
