This paper describes the capping reaction of 5'-phosphorylated oligoribonucleotides protected only by a tetrahydropyranyl group at each 2'-position.By use of the conventional capping agent PhSppm7GTMTrmM, m7G5pppGUA and m7G5'pppGUAUUA were synthesized from the corresponding oligoribonucleotide 5'-monophosphate derivatives.Since the latter was obtained in low yield because of poor solubility of the partially protected pUUA in DMF, the oligomer component was converted into a phosphorimidazolidate species which was found to be soluble in DMF and allowed to react with a newly designed capping agent, ppm7GTMTrmM.This triphosphate bond formation proceeded smoothly to give m7G5'pppGUAUUA in good yield.
