The Synthesis of Some New 7‐Methyl‐3‐substituted‐1,2,4‐triazolo[3,4‐b]benzothiazoles

Abstract

New 7‐Methyl‐3‐substituted‐1,2,4‐triazolo[3,4‐b]benzothiazoles were synthesized from p‐methylaniline to 5 with various aromatic carbonic acids. The yielded product 6a‐j was investigated with Elemental analyses, NMR, MS and IR techniques.

Synthesis of 2,2′-(p-phenylene)bisbenzazoles compounds from terephthalohydroxamoyl chloride

“…In addition, when quaternized to benzothiazolium salts, these compounds are especially active as antimicrobial, antihelmintic and antineoplastic agents and 2-alkylthio-6-aminobenzthiazoles have shown good antimycobacterial, antiyeast, anticandidous and antialgal activities. Tricyclazole is one of the benzothiazole derivatives associated with diverse bio logical activities such as application of potent anti-bacterial and fungicides for the control of Piricularia oryzae in the prevention of rice blast [1][2][3].…”
