Two series of 1,3-dioxolanes and 1,3-oxathiolane nucleosides containing N-9-oxypurine were synthesized as potential antiviral agents. These compounds were prepared by reacting the sugar moieties with iodo- or bromotrimethylsilane, followed by treatment with a mixture of sodium hydride and the desired N-hydroxy purine base. The preparation of these N-hydroxybases was also described. No significant antiviral

A new, improved procedure for the preparation of 5-amino-4- aminocarbonyl-1-hydroxyimidazole from N′-benzyloxy-N,N- dimethylformamidine and 2-amino-2-cyanoacetamide is described. O-Alkylation of this 1-hydroxyimidazole with appropriately functionalised alkyl halides or sulphonates provides an efficient route to acyclic imidazole nucleoside analogues.
