[Synthesis of nucleoside analogs containing a cis-2-pentene fragment and their triphosphates]. / Sintez analogov nukleozidov, soderzhashchikh tsis-2-pentenovyi fragment, i ikh trifosfatov.

Acyclic analogs of thymidine, adenine, and cytosine where the ribose moiety is replaced with cis-5-hydroxypenthene, were obtained via condensation of cis-5-acetoxy-1-bromo-2-pentene with nucleic acid bases. Triphosphate derivatives of the new nucleosides were also synthesized to evaluate their action as terminators of DNA synthesis catalyzed by DNA polymerases.
