Synthesis of short RNA fragments by the benzotriazolyl phosphotriester approach: Synthesis of short RNA fragments by the benzotriazolyl phosphotriester approach. Wreesmann, C. T. J.; Fidder, A.; Van der Marel, G. A.; Van Boom, J. H.Several reagents with their cas registry numbers 15074-54-1 and 17327-23-0 are used here. (Gorlaeus Lab., Leiden 2300 RA, Neth.). Nucleic Acids Res., 11(23), 8389-405 (English) 1983. CODEN: NARHAD. ISSN: 0305-1048. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Addn. of a slight excess of 2-chlorophenyl O,O-bis[1-benzotriazolyl] phosphate to a 2',5'-protected ribonucleoside gave an intermediate 3'-phosphotriester, which, after addn. of a 2'-protected ribonucleoside, afforded a dimer contg. only a 3'-5'-internucleotide bond. The above phosphorylation procedure was used in the synthesis of the pentamer UpApCpGpC. .
