Synthesis, Characterization, Thermal and Antimicrobial studies of N-substituted Sulfanilamide derivatives
Abstract Four sulfanilamide derivatives N -[4-(phenylsulfamoyl)phenyl]acetamide (1), 4-amino- N -phenylbenzenesulfonamide (2), N -[4-(phenylsulfamoyl)phenyl]benzamide (3) and N -{4-[(3-chlorophenyl)sulfamoyl]phenylbenzamide (4) were synthesized and characterized by Infra-Red (IR), Nuclear Magnetic Resonance (NMR) and UV–visible (UV–Vis) spectra. Also Liquid Chromatographic (LCMS) and High Resolution Mass Spectrometric (HRMS) methods were used. Crystal structures of 1–4 were determined by single crystal X-ray diffraction (XRD) and their conformational and hydrogen bond (HB) network properties were examined with survey of the literature data. Compounds 1 and 2 crystallize in the same orthorho…
Synthesis, characterization, crystal structures and biological screening of 4-amino quinazoline sulfonamide derivatives
Three quinazolin-4-ylamino derivatives containing phenylbenzenesulfonamides (7a-7c) were synthesized by reacting (E)-N'-(2-cyanophenyl)-N,N-dimethyl formamidine (6) with different 4- amino-N-(phenyl)benzenesulfonamides (4a-4c) and characterized by different techniques such as HRMS, IR, 1H NMR and 13C NMR spectroscopy. The structural properties were further examined by single crystal X-ray diffraction method. The X-ray data shows that compounds 7a and 7c contain two molecules and 7b contains one molecule in the asymmetric unit. Comparison of conformation of two distinct molecules, “A” and “B”, in the asymmetric unit of 7a and 7c were studied with the aid of reported literature. The in vitro …
