visible-light-induced cascade arylazidation of activatedalkenes with trimethylsilyl azide (TMSN3) has been developed. Mechanistic investigations reveal that the single electron transfer (SET) of TMSN3 with the excited photocatalyst was involved in the initial step, followed by radical addition/aryl migration/desulfonylation to furnish valuable α-aryl-β-azido amides and azidated oxindoles under mild conditions

In this study, synthesis of nine N-phenylsulfonamide derivatives was designed by starting from aniline, which is the simplest aromatic amine. These compounds were obtained in yields between 69 and 95%. Inhibitory properties of synthesized compounds on carbonic anhydrase I (CA I), CA II isoenzymes, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes were investigated. Inhibitors of
Practical chemoselective aromatic substitution: the synthesis of <i>N</i>-(4-halo-2-nitrophenyl)benzenesulfonamide through the efficient nitration and halogenation of <i>N</i>-phenylbenzenesulfonamide
the metal-promoted tandem nitration and halogenation of N-phenylbenzenesulfonamide to synthesize N-(4-halo-2-nitrophenyl)benzenesulfonamide derivatives has been developed. The method shows highly practical chemoselective and functional group compatibility. In addition, it employs insensitive and inexpensive Cu(NO3)2·3H2O, Fe(NO3)3·9H2O, and NH4NO3 as the nitrationreagents, and it provides a direct
