The fundamental roles of nucleoside triphosphates and nucleotide cofactors such as NAD(+) in biochemistry are well known. In recent decades, continuing research has revealed the key role of 5'-capped RNA and 5',5'-dinucleoside polyphosphates in the regulation of vitally important physiological processes. Last but not least, the commercial potential of nucleoside triphosphate synthesis can hardly be overestimated. Nevertheless, despite decades of investigation and the obvious topicality of the research on the chemical synthesis of the nucleotide compounds containing phosphate anhydride linkages, none of the existing procedures can be considered an up-to-date "gold standard". However, there are a number of fruitful synthetic approaches to forming phosphate anhydride linkages in satisfactory yield. These are summarized in this concise review, organized by the type of active phosphorous intermediate and reagents used.
Keywords: bioorganic chemistry; dinucleoside 5′,5′-polyphosphates; nucleoside triphosphates; nucleotides; phosphorylation.
