title: Conformation of pyridazine nucleosides: the molecular structure of 4-hydroxy-1-(beta-D-ribofuranosyl)pyridazin-6-one (3-deaza-6-azauridine).
abstract: The glycosyl torsiona angle in 4-hydroxy-1-(beta-D-ribofuranosyl)-pyridazin-6-one (or 3-deaza-6-azauridine) is in the "high-anti" region. This is similar to the torsional angles observed for 6-azapyrimidine and 8-azapurine nucleosides, but in marked contrast to those found in uridine, 3-deazauridine and other pyrimidine nucleosides.
