In the present study, a novel series of 4-pyrrol-1-yl benzoic acid hydrazide analogs, some derived 5-substituted-2-thiol-1,3,4-oxadiazoles, 5-substituted-4-amino-1,2,4-triazolin-3-thione and(More)
A novel 6,8-dichloro [1,2,4]triazolo [3,4-b] [1,3]benzoxazole-3(2H)-thione 4 and its derivatives 5a and 5b are synthesized from 5,7-dichloro-2-hydrazinyl-1,3-benzoxazole 3, obtained by reaction of(More)
Condensation of 5,7-dichloro-2-hydrazino-1,3-benzoxazole 3 with different aromatic acetophenones in methanol using catalytic amount of glacial acetic acid afforded the corresponding(More)
5,7-Dichloro-1,3-benzoxazole-2-thiol and its novel derivatives that have previously been synthesized in our laboratory are screened for in vitro antibacterial activity. In correlation to(More)
Novel 5-nitro-1, 3-benzoxazole derivatives (2–8) are synthesized from 5-nitro-1,3-benzoxazole-2-thiol 1. The newly synthesized compounds are characterized by analytical 1H NMR, 13C NMR, LC–MS mass(More)
