A facile method has been implemented for the synthesis of different N-substituted sulfamoylacetamides (3a-q) by the reaction of 4-acetamidobenzenesulfonyl chloride with a series of different alkyl/aralkyl/aryl amines in aqueous alkaline media under dynamic control of pH at 9-10. The structures of the synthesized N-substituted sulfamoylacetamides were elucidated through spectral analysis like FT-IR, EIMS and 1H-NMR. The synthesized derivatives were further screened against Chymotrypsin enzyme. The results revealed that most of the synthesized compounds were found to be potent chymotrypsin...

Different N-substituted sulfonamides were synthesized by reacting 4-Chloro-benzenesulfonyl chloride with 2-Methoxy aniline and 2-Ethyl-6-methyl aniline to form 4-chloro-N-(2-methoxyphenyl)benzenesulfonamide and 4-chloro-N-(2-ethyl-6-methylphenyl)benzene-sulfonamide respectively. Different N-substituted alkyl/aryl derivatives were synthesized using 4-chloro-N-(2-methoxyphenyl)benzenesulfonamide and 4-chloro-N-(2-ethyl-6-methylphenyl)benzenesulfonamide to yield 4-chloro-N-ethyl-N-(2-methoxylphenyl) benzenesulfonamide, N-benzyl-4-chloro-N-(2-methoxyphenyl) benzenesulfonamide,...

Different analogues of Benzotriazoles and Benzimidazoles were synthesized using different O-phenylene diammines as main reactant and further analogues were prepared by substituting the benzene ring and the heterocyclic ring of the above mentioned benzo-fused moieties using reagents e.g. chloroacetic acid, halogenating agents and hydrazine. Characterization of the synthesized compounds was done by IR and NMR spectroscopic techniques. The synthesized compounds were also screened for antimicrobial activity and were found to have significant antifungal and antibacterial activity against...

Sulfonamides are considered to be pharmaceutically important class of compounds. In the present work, N-(2,4-dimethylphenyl)-4-toluenesulfonamide was synthesized by the reaction of 2,4-dimethylaniline and 4-tosyl chloride (4-methylbenzenesulfonyl chloride) using 10% aqueous Na2CO3 solution as reaction medium. At the second step, the synthesized molecule was made to react with different alkyl/aralkyl halides to yield the target compounds, using N, N-dimethylformamide (DMF) as reaction medium and lithium hydride as an activator. The synthesis of all the compounds was verified by spectral...
