The synthesis of diimidotriphosphoric acid and a series of regioselectively protected esters is described. This opens an unprecedented route for the preparation of various nucleotide and dinucleotide analogs and related compounds.
The first synthesis of fully deprotected diimidotriphosphoric acid is described. The PNPNP sequence is obtained from an all protected cyclic precursor that can be regioselectively mono- or bis-functionalized with alcohols and amines in classical organic solvents. All protective groups can be removed at the end of the synthesis by catalytic hydrogenation to afford the corresponding PNPNP derivatives as a salt. The strategy developed allows a straightforward access to a new class of nucleotide and dinucleotide analogs as well as other triphosphorylated compounds of biological relevance.
