Abstract

Older synthetic procedures for nebularine (la) involved chloromercuripurinide fusion reactions with sugar derivatives such as chlorc~ triacetoribofuranose,~ modified fusion reactions, 6 and longer syntheses involving catalytic hydrogenation of ring-halogenated materials7 or of thioinosine. 8 Access to 9-alkylpurines from 9-alkyladenines or from other corresponding purines was previously limited. Such routes included alkylation of purine ...
