Design, synthesis and screening of some novel benzoxazole based 1, 3, 4-oxadiazoles as potential antimicrobial agents

    • 通讯作者: Raghu Vardhan Reddy Mekala,
摘要: A series of novel 2-(5-substituted-[1,3,4]oxadiazol-2-yl)-benzoxazoles (7a-h) were synthesized in good yields in two different directions by involving benzoxazole-2-carboxylic acid (1) as raw material and benzoxazole-2-carbonyl chloride (2), benzoxazole-2-carboxylic acid methyl ester (3), benzoxazole-2-carboxylic acid hydrazide (4), benzoxazole-2-carboxylic acid N'-acetyl hydrazide (5a-d) and benzoxazole-2-carboxylic acid-ethylidene-hydrazides (6a-d) as reactive intermediates. The chemical structures of all the synthesized compounds were elucidated by their IR, 1H NMR and 13C NMR and mass spectral data. Further, the target compounds were screened for their antimicrobial activity against various Gram-positive and Gram-negative bacteria.
