SYNTHESIS AND STRUCTURE DETERMINATION OF SOME ESTER AND HYDRAZIDE CONTAINING BENZOTHIAZOLE FROM 4-HYDROXYBENZALDEHYDE
Main Article Content
Abstract
In this paper, two esters 5a, 5b and two hydrazides 6a, 6b containing benzothiazole were successfully synthesized from 4-hydroxybenzaldehyde, in which the benzothiazole ring closure was assisted by microwave energy irradiation. The structures of these four compounds were determined by modern spectroscopic methods such as IR, NMR and MS. The antibacterial activity test results showed that both samples 6a, 6b had moderate and weak activities against some bacterial or fungal strains.
