5'-O-Benzoyl-3'-(tetrazole-2"-yl)-3'-deoxythymidine and its 5"-substituted derivatives were obtained by the reaction of 5'-O-benzoyl-2, 3'-anhydrothymidine with triethylammonium salts of either tetrazole or 5-substituted tetrazoles. Debenzoylation of these compounds yielded 3'-(tetrazole-2"-yl)-3'-deoxythymidine and its 5"-derivatives. Structures of two of them were confirmed by X-ray analysis. Both 3'-(tetrazole-2"-yl)-3'-deoxythymidine and 3'-(5"-methyltetrazole-2"-yl)-3'-deoxythymidine have anti-conformation with respect to the glycosidic bond, and 2'-endo-3'-exo-conformation of the sugar residue with gauche+ orientation relative to the C4'-C5' bond. 3'-(Tetrazole-2"-yl))-3'-deoxythymidine 5'-triphosphate exhibited poor termination substrate properties towards avian myeloblastosis virus reverse transcriptase and did not serve as a substrate for other employed DNA polymerases.
