Relevant academic research and scientific papers

A microwave-assisted approach to N-(2-nitrophenyl)benzenesulfonamides that enhanced peroxidase activity in response to excess cadmium

A facile and efficient approach to N-(2-nitrophenyl) benzenesulfonamides was developed under microwave irradiation. A series of pyrabactin analogues containing nitrophenyl scaffold was obtained in excellent yields. In addition, the method was pretty suitable to prepare flusulfamide. Significantly, the 3ae could enhance POD activity in response to heavy metal stress.

Chemoselective nitration of aromatic sulfonamides with tert-butyl nitrite

A methodology for the efficient conversion of aromatic sulfonamides into their mono-nitro derivatives using tert-butyl nitrite is reported. The reaction exhibits a high degree of chemoselectivity for sulfonamide functionalized aryl systems, even in the presence of other sensitive or potentially reactive functionalities.
