Two novel cyclic dinucleosides having two butylene linkers between the 5′-OH and N-3 positions (thereby generating a 24-membered ring) were synthesized from uridine via tandem cross-metathesis and ring-closingmetathesis. Selective synthesis of one dinucleoside with a link between the two N-3 atoms and a link between the two 5′-OH groups was achieved.

Novelcyclonucleoside analogues of uridine having pentylene and hexylene linker between the 5′-O and 3-N positions (thereby generating a 13- and 14-membered ring, respectively) were synthesized from uridine via ring-closing metathesis. An example of cyclic dinucleosides having two butylene linkers between the 5′-O and 3-N positions (24-membered ring) was synthesized from uridine via tandem cross-metathesis
