Synthesis of the C-nucleoside, 5-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-1-methyluracil, isosteric to the potent antiviral and anticancer nucleoside, 1-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-1-methyluracil (2'-fluoro-5-methyl-ara-U or FMAU) was achieved by exploitation of the 4,5'-anhydro-nucleoside. Attempts at application of this ribosyl-to-arabinosyl pyrimidine transformation to 2,5'-anhydrouridine resulted in the formation of 2,2'-anhydro-5-substituted-arabinosyluracil.

UI MeSH Term Description Entries
D007202 Indicators and Reagents Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.
