Transient protection of both the 3’- and 5’-hydroxyl groups of la or of the 3’-hydroxyl group of lb, followed by Mitsunobu alkylation with 2-(4-nitrophenyl)ethanol gave the 06-protected nucleosides 4a or 4b in good yield in a one-flask procedure. Similar reactions with 3-hydroxypropionitrile or 2-(phenylsulfonyl) ethanol, however, were unsuccessful. Reaction of lb without 3’-hydroxyl protection led to formation of a stable N3 → 3’ cyclonucleoside, 7a.
