o-Nitrobenzyl group was introduced to the 2′-hydroxyl function of uridine via 2′, 3′-O-(dibutylstannylene) uridine. The benzylated uridine was protected at the 5′-hydroxyl group with monomethoxytrityl chloride and condensed with 2′,3′-O-dibenzoyluridine 5′-phosphate or N, N′,2′,3′-O-tetrabenzoyladenosine 5′-phosphate using dicyclohexylcarbodiimide (DCC). o-Nitrobenzyl ether linkage of the dinucleotides was removed by UV irradiation with wavelength longer than 320 nm. Deprotected UpU and UpA thus obtained were characterized by RNase A digestion.
