1-methyl-5-nitro-imidazoles bearing a trisubstituted ethylenic double bond in the 2 position. These compounds are ascribed to a C-alkylation reaction according to the SRN1 mechanism followed by base-promoted nitrous acid elimination.

1-Methyl-2-chloromethyl-5-nitroimidazole reacts by an S(RN)1 mechanism with various aliphatic, cyclic or heterocyclic nitronate anions to afford, in high yields, new 5-nitroimidazoles bearing a trisubstituted ethylenic double bond at the 2 position. Some of these compounds are as active as metronidazole in vitro and in vivo against protozoa and anaerobic bacteria. Structure-activity relationships are discussed.
