Synthesis and stability of strongly acidic benzamide derivatives
Reactivity studies of strong organic acids based on the replacement of one or both of the oxygens in benzoic acids with the trifluoromethanesulfonamide group are reported. Novel derivatives of these types of acids were synthesized in good yields. The generated N-triflylbenzamides were further functionalized through cross-coupling and nucleophilic aromatic substitution reactions. All compounds w...
متن کاملDesign, synthesis and antimicrobial evaluation of novel benzoxazole derivatives.
The synthesis of (S)-2-(4-tert-butylphenoxy)-3-(benzoxazol-5-yl) propanoic acid derivatives (2a-k) were described and their in vitro antibacterial activities were determined against Gram-negative and -positive bacteria. These compounds were found to exert a broad spectrum of activity against the screened bacteria, but poor MIC values were found for Candida albicans fungi. Compound 2b bearing a ...
متن کاملCrystal Structure and Stereochemistry Study of 2-Substituted Benzoxazole Derivatives
The structure of 2-[(4-chlorophenylazo) cyanomethyl] benzoxazole, C15H9ClN4O (I), has triclinic ([Formula: see text]) symmetry. The structure displays N-H ⋯ N hydrogen bonding. The structure of 2-[(arylidene) cyanomethyl] benzoxazoles, C17H10N2O3 (II), has triclinic ([Formula: see text]) symmetry. The structure displays C-H ⋯ N, C-H ⋯ C hydrogen bonding. In (I), the chlorophenyl and benzoxazole...
متن کاملInvestigation of dibromo and N-bromoacetyl derivatives of [b] carbazole-synthesis and antibacterial evaluation
The synthesis, structure and biological activity of carbazole compounds has been long focus of research interests in the field of medicinal chemistry. 5,8-dibromo-5,6-dihydro(3,2-a)carbazole A have prepared in good yield by a free radical bromination reaction of 8-bromo-5,6-dihydro9(3,2-a)carbazole with N-bromosuccinimide in carbontetrachloride at ambient temperature.. Compound 2 have prepared ...
متن کاملDesign, Synthesis and Anticancer Screening of Novel Pyrazole Derivatives Linking to Benzimidazole, Benzoxazole and Benzothiazole
Substituted aromatic amines were diazotized followed by coupling with malononitrile to afford substituted phenyl hydrazono-malononitrile compounds 2a-c. Compounds 3a-c were prepared through the reaction of substituted phenyl hydrazono-malononitriles 2a-c with phenyl hydrazine, while the reaction of compounds 2a-c with hydrazine hydrate afforded diamino compounds 4a-c. The diamino compounds 4a-c...
