A novel cyclouridylic acid 1 having a propylene bridge between the uracil 5 position and the 5′-phosphate group was synthesized. The structure of 1 was analyzed by 1H NMR, and CD spectroscopy, which suggested that the cyclonucleotide 1 was highly stabilized in a considerably rigid g′/C3′-endo conformation with the base orientation of and. The molecular mechanics calculation of 1 gave a similar conclusion.
