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

Huang, Zhi-You,Liu, Min,Mao, Yi-Jun,Chen, Yu-De,Wang, Yan-Ping,Liu, Chong

supporting information, p. 626 - 629 (2019/02/01)

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.
