Synthesis of 5'(3')-O-amino nucleosides. 1985

K Kondo, and T Ogiku, and I Inoue

Synthetic methods leading to 5'(3')-O-amino nucleosides have been developed in an effort to prepare derivatives that may have antitumor or antiviral activities. They are based on ring opening of O2,5'-cyclonucleosides with the N-protected hydroxylamines and dehydrative coupling of 5'(3')-O-unprotected nucleosides with N-hydroxyphthalimide.

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.
