Abstract

The use of adenosine N-oxide derivatives to prevent intramolecular cyclization during nucleophilic displacement reactions on the sugar moiety is described. This new synthetic use of “-oxides is illustrated by the synthesis of 5'-0-(p-toluenesulfonyl)-2', 3'-O- isopropylideneadenosine IP-oxide (6) and subsequent displacement of the 5'substituent with iodide or azide under conditions which lead exclusively to N34'intramolecular ...
