Ribosylation and glucosylation of the base residues of inosine and uridine
have been efficiently achieved using Mitsunobu reaction, leading to the N-1
and 6-O-glycosylinosine and N-3-glycosyluridine derivatives, all with beta
configuration at the glycosidic carbon. The unprecedented 5-amino-1-(beta-
D-ribofuranosyl)imidazole-4-[ N-(beta-D-glucopyranosyl)carboxamide] has als
o been synthesised.
