Abstract
An oligouridylate with chain-length of more than three was condensed on a polyadenylate [poly(A)] template with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDAC) in imidazole buffer. The condensation reaction proceeds via the phosphorimidazolide of the oligouridylate as an intermediate. Pentauridylate [(pU)5] was converted to decauridylate [(pU)10] in 10% yield at 0 degree C for 7 days in the presence of the poly(A) template, while no coupling product was obtained in the absence of the poly(A) template. The resulting linkage of the (pU)10 was mainly 2'-5' linkage.Entities:
