A number of synthetically useful transformations have been developed to generate novel 5′‐peptidyl nucleoside monophosphate analogues that incorporate sensitive phosphoaminal, ‐hemiaminal or ‐hemithioaminal functionalities. The strategies adopted entailed the coupling between dipeptides, which enclose a reactive Cα‐functionalized glycine residue and phosphate or phosphorothioate moieties. These developments led to potentially powerful and general methodologies for the preparation of α‐phosphorylated pseudopeptides as well as nucleoside monophosphate mimics. The resulting conjugates are of interest for a variety of important applications, which range from drug development to synthetic biology, as pronucleotides or artificial building blocks for the enzymatic synthesis of xenobiotic information systems. The potential of all dipeptide‐TMP conjugates as pyrophosphate mimics in the DNA polymerization reaction was tested, and the influence of the nature of the linker was evaluated by in vitro chain elongation assay in the presence of wild‐type microbial DNA polymerases.
