- A novel class of O6-(benzotriazol-1-yl)inosine as well as the corresponding 2‘-deoxy derivatives can be conveniently prepared by a reaction between sugar-protected or -unprotected inosine or 2‘-deoxyinosine nucleosides and 1H-benzotriazol-1-yloxy-tris(dimethylamino)phosphonium hexafluorophosphate
- The reaction appears to proceed via a nucleoside phosphonium salt, and in the absence of any additional nucleophile, the released 1-hydroxybenzotriazole undergoes reaction with the formed phosphonium salt leading to the requisite O6-(benzotriazol-1-yl)inosine or 2‘-deoxyinosine derivatives
- A fully protected DNA building block, the O6-(benzotriazol-1-yl)-2‘-deoxyinosine 5‘-O-DMT 3‘-O-phosphoramidite, has been prepared and a preliminary evaluation of its use for DNA modification has been performed. Results from these studies indicate several important facts: A single, simple methodological approach provides a class of stable, isolable ribo and 2‘-deoxyribonucleoside derivatives that possess excellent reactivity for SNAr chemistry with a wide range of nucleophiles
- A benzotriazolyl nucleoside phosphoramidite appears to be a suitable reagent for incorporation into DNA for purposes of site-specific DNA modification
