(D)- and (L)-cyclohexeneyl-G were synthesized enantioselectively starting from (R)-carvone. Both show potent and selective anti-herpesvirus activity (HSV-1, HSV-2, VZV, CMV). Molecular modeling demonstrates that both isomers are bound in the active site of HSV-1 thymidine kinase in a high-energy conformation with the base moiety orienting in an equatorial position. It is believed that the flexibility

Both enantiomers of cyclohexenylguanine were synthesized in a stereospecific way starting from the same starting material: R-(-)-carvone. Both compounds showed potent-and selective anti-herpesvirus activity (HSV-1, HSV-2, VZV, CMV). The binding of both cyclohexene nucleosides in the active site of HSV-1 thymidine kinase was investigated, and a model for the binding of both enantiomers is proposed. The amino acids involved in binding of the optical antipodes are the same, but the interaction energy of both enantiomers is slightly different. This may be attributed to the interaction of the secondary hydroxyl function of the nucleoside analogues with Glu-225. Structural analysis has demonstrated the flexibility of the cyclohexenyl system, and this may be considered as an important conformational characteristic explaining the potent antiviral activity.

A Straightforward Stereoselective Synthesis of <scp>d</scp>- and <scp>l</scp>-5-Hydroxy-4-hydroxymethyl-2-cyclohexenylguanine
A novel and facile synthesis of 5-hydroxy-4-hydroxymethyl-2-cyclohexenylguanine 1 is described. The key steps involve a Diels-Alder reaction of ethyl (2E)-3-acetyloxy-2-propenoate 2 as dienophile with Danishefsky's diene 3 to build up the six-membered ring skeleton, a Fraser-Reid reductive rearrangement of the adduct using LiAlH(4), and base-moiety introduction using a Mitsunobu reaction.
