A novel systematic approach to the synthesis of 2-cyano-7-deaza-8-azapurinederived nucleosides is described. It is shown how this chemistrywas developed with the labile 2-substituted nitrile position inmind, and also how the same approach is applicable to 2-cyano-8-azapurinederived nucleosides.

Modified purine analogs of GS-9148 [5-(6-amino-purin-9-yl)-4-fluoro-2,5-dihydro-furan-2-yloxymethyl]-phosphonic acid (2'-Fd4AP) were synthesized and their anti-HIV potency evaluated. The antiviral activity of guanosine analog (2'-Fd4GP) was comparable that of to 2'-Fd4AP in MT-2 cells, but selectivity was reduced.
