New 5-nitroimidazoles bearing lactame nucleus: Synthesis and antibacterial properties

Article abstract of DOI:10.1016/0223-5234(91)90118-7

New 5-nitroimidazoles bearing a trisubstituted ethylenic double bond in position 2 were prepared by reacting various 1-alkyl-2-chloromethyl-5-nitroimidazole with 3-nitrolactam anions by S(RN)1 mechanism in phase-transfer catalysis conditions. These compounds showed in vitro and in vivo antianaerobic activity which was clearly greater than that of metronidazole. Structure-activity relationships have been discussed.
