One-pot synthesis of symmetrical dinucleoside polyphosphates and analogs via 4,5-dicyanoimidazole-promoted tandem P–O coupling reactions

A novel one-pot protocol for the synthesis of symmetrical dinucleoside tri-, tetra-, and pentaphosphates, and their phosphonate analogs simply from nucleoside 5′-phosphoropiperidates has been developed by utilizing 4,5-dicyanoimidazole-promoted tandem P–O coupling reactions.
