Ribosyluronic acid uracil, 5-nitro

C9H9N309-H20 5-Nitro-l-(/ -D-ribosyluronic acid)uracil, monohydrate (NRURAM11)140... [Pg.274]

The studies of Levene and LaForge60 on the nitration of uridine have since been re-investigated. It had been reported, several decades ago, that treatment of uridine with nitric acid produced a Nitro-Uridin-Carbon-saure which was stated to be a dimer containing an anhydro typeof linkage (positions unspecified) between two nucleoside residues.60 According to an abstract,269 this compound has now been identified as the monomeric 5-ni-tro-l-(/8-D-ribosyluronic acid)uracil (CXXII) this was converted to the isopropyl ester and the 2,3-O-isopropylidene acetal thereof. Nitration of the pyrimidine moiety of uridine without oxidation of the 4-(hydroxy-... [Pg.358]

In the only neutron diffraction study of a (heavily modified) nucleoside, 5-nitro-1 -09-D-ribosyluronic acid)-uracil monohydrate [466], there is a complicated scheme of hydrogen bonds which involves two-center and three-center C-H 0... [Pg.157]
