The syntheses of the novel acyclicnucleosides 5a–5m, carrying different N-[(benzyloxy)(aryl)methyl] substituents, are described (Scheme). These compounds could be prepared in medium-to-good yields by either direct or silyl-assisted coupling of the electrophiles 6 with either purine or pyrimidine nucleobases, or with different imidazole derivatives. The reactivity of the positively charged electrophilic
