Abstract

A C-nucleoside analog of cordycepin, 6-amino-8-(3-deoxy-β-D-erythro-pentofuranosyl)purine (6), has been synthesized. 3-Deoxy-2,5-di-O-(p-nitrobenzoyl)- β-D-erythro-pentofuranosyl bromide reacted with mercuric cyanide in nitromethane to give 2,5-anhydro-4-deoxy-3,6-di-O-(p-nitrobenzoyl)-D-ribo-hexononitrile which, after acid hydrolysis and removal of the protecting groups, afforded 2,5-anhydro-4-deoxy-D-ribo-hexonic acid. Reaction of this acid with 4,5,6-triaminopyrimidine gave the corresponding amide, which was pyrolyzed to give compound 6. The mass- and n.m.r.-spectral data for the synthesized analog are quite similar to those of the natural antibiotic. © 1974.
