A novel systematic approach to the synthesis of 2-cyano-7-deaza-8-azapurine
derived nucleosides is described. It is shown how this chemistry
was developed with the labile 2-substituted nitrile position in
mind, and also how the same approach is applicable to 2-cyano-8-azapurine
derived nucleosides.
nucleosides - nitriles - protecting groups - heterocycles - glycosylation
