Synthesis and antiviral activity of the title fluoromethylenecyclopropane analogues 15a, 15b, 16a, and 16b is described. Methylenecyclopropane carboxylate was first transformed to 2,2-bis-hydroxymethylmethylenecyclopropane. Selective monoacetylation followed by introduction of fluorine gave 2-acetoxymethyl-2-fluoromethylmethylenecyclopropane as the key intermediate. The synthesis of analogues 15a, 15b, 16a, and 16b then followed alkylation-elimination procedure as described previously for other methylenecyclopropane analogues [corrected] Compounds 15a, 15b, 16a and 16b were not active against Epstein-Barr virus (EBV) [corrected] Analogue 15a inhibited hepatitis C virus by virtue of its cytotoxicity and it moderately inhibited replication of the Towne strain of human cytomegalovirus (HCMV). The E-isomer 16a was a substrate for adenosine deaminase, whereas the Z-isomer 15a was not deaminated.
