Synthesis of (Z)-(2,3-bis-hydroxymethyl)methylenecyclopropane analogues of nucleosides adenosine10a,10b,10cand17is described. Epimerization of Feist's acid (11) using acetic anhydride gave cyclic anhydride12which was reduced in situ to give diol13. Acetylation (compound14) followed by addition of bromine led to dibromo derivative15. Alkylation-elimination of adenine with15afforded, after deacetylation, analogue10a. Similar treatment of 2-amino-6-chloropurine and 2,6-diaminopurine led to diacetates16and18. Deprotection then gave compounds17and10c. Hydrolysis of17furnished guanine analogue10b. Compounds10a,10bor10cwere inactive against HCMV, HSV-1, HSV-2, EBV, VZV and HBV. Analogues10aand10bwere also assayed for anti-HIV activity. Compound10awas effective in HIV-1/MT-2 culture with EC50/CC5033/> 100 µM but10bwas inactive. Analogue10awas not a substrate for adenosine deaminase.
