Application
Solid-phase Synthesis of DNA and RNA 5'-O-Triphosphates

After oligonucleotide synthesis:
5-Chloro-saligenyl-N,N-diisopropylphosphoramidite (Reagent I, C3326) is coupled to the 5'-end of the DMT-off oligonucleotide. Oxidation of the formed 5'-phosphite using the same oxidizing reagent used in standard oligonucleotide synthesis leads to support-bonded 5'-cycloSal-oligonucleotides. Reaction with pyrophosphate (Reagent II, B5440) yields the corresponding 5'-triphosphates. The 5'-triphosphorylated oligonucleotides are obtained after cleavage from the support in high purity and excellent yields. The whole reaction sequence was adapted to be used on a standard oligonucleotide synthesizer.
