title: Green route for the heterocyclization of 2-mercaptobenzimidazole into beta-lactum segment derivatives containing -CONH- bridge with benzimidazole: Screening in vitro antimicrobial activity with various microorganisms.
abstract: The efficient and rapid synthesis of novel azetidin-2-ones 4a-j has been established. Thus, both microwave and conventional condensation 2-{(1H-benzimidazol)-ylthio}-N'-2-(substituted phenyl) hydrazide with chloroacetylchloride were carried out in DMF-benzene solvent in the presence of Et(3)N catalyst. The microwave synthesis route afforded better yield with short time. The novel heterocycles were characterized by elemental analysis and spectral features. Some of the produced compounds were screened for their antimicrobial activity.
