Abstract

Abstract Translated from German Erfindungsgemäss werden 5'-Ester von Pyrimidinnucleo siden der allgemeinen Formel worin R' eine Methylgruppe oder ein Jodatom, R 2 ein Wasserstoff oder eine Hydroxylgruppe, R 3 eine verzweigte oder unverzweigte Alkylgruppe von 1 bis 17 C-Atomen, Cycloalkangruppe mit 5 bis 10 C-Atomen oder eine Phenylgruppe bedeuten, bereitgestellt. According to the invention 5'-esters of pyrimidine nucleosides of the general formula wherein R 'is a methyl group or an iodine atom, R 2 is a hydrogen or a hydroxyl group, R 3 is a branched or unbranched alkyl group of 1 to 17 carbon atoms, cycloalkane group having 5 to 10 carbon atoms or a phenyl group. Diese Ester erhält man durch Umsetzung des entsprechender Nucleosids mit den entsprechenden Carbonsäurederivaten. Die Ester sind in der Pharmazie einsetzbar und zwar in Arzneimitteln als antivirale Wirkstoffe. These esters are obtained by reacting the corresponding nucleoside with the corresponding carboxylic acid derivatives. The esters can be used in pharmacy and in pharmaceuticals as antiviral agents.
