The present communication deals with the synthesis of a series of 2-acetyl-2-ethoxycarbonyl-1-[4(4'-arylazo)-phenyl]-N,N-dimethylaminophenyl aziridines. The compounds were synthesized in excellent yields (70-80%) and the structures were established on the basis of consistent IR, H-1 NMR and elemental analysis data. The purity has been ascertained by chromatographic resolution using acetic acid-toluene (6:4 v/v) as binary eluent. All the compounds have been tested for their antimicrobial activity against a representative panel of bacteria i.e. Bacillus subtilis, Escherichia coli, Pseudomonas diminuta and Staphylococcus aureus using azinomycin as reference drug. All the synthesized compounds were found to exhibit profound antimicrobial activity. (C) 2008 Elsevier Masson SAS. All rights reserved.

l)-4-phenyl azetidin-2-one were synthesized through the reaction of N-4-[phenyldiazenyl] phenyl}-N-[phenyl methylene] amine with 4-[phenyldiazenyl] aniline. The resulting 3-chloro-4-phenyl-1-4-[phenyldiazenyl] phenyl} azetidin-2-one intermediate in benzene was irradiated in a Pyrex vessel with 350 nm UV light in a photochemical reactor to give the desired derivatives (4a–j). Structures of the new
