A number of imines derivatives have been synthesized, they were obtained by condensation of aromatic aldehyde derivatives with primary aromatic amine derivatives. Their structures have been characterised by IR,1H NMR in addition to the elemental analysis. The biological activity of these imines (which are also known as Schiff bases) were examined against different type of microorganisms and they found to have considerable activity in comparison with the most commonly used antibiotics.

The interaction between 1,3-dioxolane with primary aromatic amine- sulfanilamide (streptocide), secondary aromatic amine-N-benzylaniline and also with amine of heterocyclic series – 4-aminopyridine. It is found that, sulfanilamide (streptocide), which has an electron withdrawing sulfonamide group in para position, reacts with 1,3-dioxolane in an atmosphere of benzol and trifluoroacetic acid producing 3-(4-sulfamoylphenyl)-3,4-dihydroquinazoline-6-sulphonamide, that is corresponding to the previous result obtained when 1,3-dioxolane reacts with para-nitroaniline (which also contains electron-withdrawing nitrogroup) resulting in 3-(p-nitrophenyl)-6-nitro-3,4-dihydroquinazoline. Under the same conditions the interaction between 1,3-dioxolane and N-benzylaniline results in producing 4,4'-bis(phenylmethyleneamino)diphenylmethane, which refers to a different class of compounds – diphenylmethane derivative. A primary amine of heterocyclic series 4-aminopyridine reacts with 1,3-dioxolane in the presence of concentrated hydrochloric acid producing N,Nʹ-di-(4-pyridinyl)methylenediamine. Antimicrobic properties of received compounds were studied on museum potentially pathogenic microorganism strains: Staphylococcusaureus (strain 906), Candid aalbicans (АТСС 24433), in FSBI «Scientific Centre for Expert Evaluation of Medicinal Products» of the Ministry of Health of the Russian Federation. Only N,Nʹ-di-(4-pyridyl)methylenediamine out of three investigated compounds showed microbiological activity. This compound inhibits growth of Staphylococcus aureus at concentration 62.5 µg/ml, culture death comes from the effect of concentration 125.0 µg/ml. The morphology of compounds was established according to mass spectrometry data, 1Н NMR spectroscopy, the structure of N,Nʹ-di-(4-pyridyl)methylenediamine in the form of chloride was proved using X-ray structural analysis.
