Abstract

A process is disclosed for the preparation of optically active purine nucleosides, particularly nucleosides of formulae 1 and 2, nucleoside analogs and optically active intermediates of formula 3 which may be used in the preparation of nucleosides of the formula 4 as well as a purine nucleosides and nucleoside analogs. ##STR1## The process is directed to the preparation of such compounds, including novel such compounds in their respective .alpha.- and .beta.-anomeric forms, and the enantiomeric forms of these compounds. These compounds show various levels of anti-viral and/or anti-cancer activity.
