Abstract:

Perimidine is a multi-nuclear N-heterocyclic compound, which plays an important role in industrial and biological fields. Perimidines have been drawn extensive examinations from many researchers for a long time due to the nitrogen heterocyclic ring. Here, a series of perimidine derivatives(4a~4g and 6) was synthesized through 1,8-diaminonaphthalene and aldehydes. The products were characterized by infrared spectroscopy(IR), proton or carbon nuclear magnetic resonance(1H NMR, 13C NMR), high resolution mass spectrometry(HRMS). Compounds 4a and 6 were investigated by single-crystal X-ray diffraction. X-ray analysis reveals that both of crystals of 4a and 6 are made up of monoclinic unit cells with space group P21/n. In addition, the biological activity assay was carried out. The results show that perimidine derivatives have a diverse range of biological activities against the fungi, which indicates that perimidine derivatives have great potential applications in antibacterial fields in the future. And test data indicate that there is no obvious regulation between fungicidal activity and the different substituents on the benzene ring.
