The reaction of 2-(cyanomethyl)benzonitrile (1) with different diazonium salts gave the corresponding aryldiazenyl derivatives 2a–e which reacted with sodium hydroxide and ethyl chloroacetate and hydroxylamine hydrochloride to afford the corresponding acetamides 4a–e, pyrazoloisoquinolines 6a–e and triazoloisoquinoline derivatives 8a–e, respectively. Moreover, the reaction of 1 with arylidene malononitriles 9a–c afforded dihydronaphthalenes 11a, b and naphthalene derivative 12, respectively. The newly synthesized compounds were characterized by analytical and spectral data. The investigated compounds were screened for their antibacterial activity against Gram-positive bacteria, Gram-negative bacteria and antifungal activity. Among the synthesized compounds, (E)-2-(cyano((4-nitrophenyl)diazenyl)methyl)benzonitrile (2e) exhibited a significant activity toward both Gram-positive, Gram-negative bacteria and exhibit the most potent in vitro antifungal with MIC's (6.25 μg/mL) against Botrytis fabae.
Novel series of azodyes, pyrazoloisoquinolines, triazoloisoquinolines and dihydronaphthalenes were synthesized. Compound 2e showed a significant antimicrobial activity.Figure optionsDownload as PowerPoint slideHighlights
