Abstrakt: Conformation of pyrroPME nucleotide analogues was studied by means of NMR at different pD values in D2O solutions. Surprisingly, two stable conformers were found at pD > 9 for both cis and trans configurations and their ratio depended on the acid-base properties of nucleobase attached to pyrrolidine ring. The results of conformational analysis suggest that the conformation of the pyrrolidine ring is locked via intramolecular hydrogen bond between negatively charged phosphonate oxygen atom and protonized pyrrolidine nitrogen.
