摘要: Nucleoside analogues containing a 1,3-dioxolane structure are suitable antiviral agents, particulary for the treatment of the HIV infections in mammals, especially humans. Examples of the nucleoside analogues include: cis-2-acetoxymethyl-4-(thymin-1′-yl)-1,3,-dioxolane, cis-2-hydroxymethyl-4-(thymin-1′-yl)-1,3-dioxolane, cis-2-benzoyloxymethyl-4-(cytosin-1′-yl)-1,3-dioxolane, and cis-2-hydroxymethyl-4-(cytosin-1′-yl)-1,3-dioxolane. These compounds can be in the form of their racemates or their separate enantiomers.
