A new series of imidazole-containing.1, 5-benzodiazepines have been synthesized by the condensation of chalcones with o- phenylenediamine using.piperidine in polyethylene g.ycol （PEg.400） as an efficient and g.een reaction solvent. The advantag.s of this protocol are environmental friendliness, easy work-up, hig. yields, mild reaction condition and avoidance of expensive catalyst. Furthermore, newly synthesized compounds were evaluated for their antimicrobial activity.
