Synthesis of 2'- or 3'-o-(4-methoxybenzyl)nucleosides and its application in the 3'-terminal nonanucleotide sequence of rous sarcoma virus 35S RNA synthesis
2'- or 3'-O-(4-Methoxybenzyl)nucleoside derivatives were synthesized by treatment of uridine, N4-benzoylcytidine, N6-benzoyladenosine, and N2-benzoylguanosine with 4-methoxy-phenyldiazomethane. The separation of 2'- or 3'-isomers became possible on a silica gel column chromatography by using N-acylated nucleosides and these compounds could be used as useful starting materials for the synthesis of
