Webpyrophosphate as the nucleophile. This approach, developed by Poulter and co-workers [17], forms a cornerstone in the armoury towards the synthesis of nucleoside-5’-polyphosphates [4]. The key element to the success of this process is the avail-ability of dry, organic-solvent-soluble pyrophosphate. Tris(tetrabutylammonium) pyrophosphate is ... WebAug 20, 2014 · In a one-pot fashion, without isolating the intermediate 2, to the same flask, a prechilled cocktail containing tributylammonium pyrophosphate, tributylamine, and acetonitrile was added to the reaction mixture. The reaction mixture was quenched by slow addition of ice-cold water followed by extraction with dichloromethane.

WebTreatmentofthe nucleotidemorpholidatewith tributylammonium pyrophosphate yielded the triphosphate (aATP) (34). The triphosphate was than dissolved in H 2 O and applied to a Sephadex column (Sephadex A-25 in the HCO 3 – form). A linear gradient of TEAB (0–0.5 M TEAB) was used to elute the product. Following collection of the major ... WebPhosphoroselenoate RNA (PSe-RNA) is nuclease resistant and has great potentials in X-ray crystal structure and function studies of noncoding RNAs and protein–RNA interactions.
