A photoredox-catalyzed three-component synthesis of N-aminosulfonamides starting from diaryliodonium salts, hydrazines and sulfur dioxide is reported. This reaction proceeds under mild conditions at room temperature and is driven by visible light. A simple bisulfite salt can be used as a readily available and easy-to-handle sulfur dioxide source. Mechanistic studies support a catalytic photoredox pathway with the diaryliodonium salt as convenient source for aryl radicals. (Figure presented.).

The coupling of aryldiazonium tetrafluoroborates, DABCO×(SO 2)2, and hydrazines under metal-free conditions leads to the formation of aryl N-aminosulfonamides. The reaction proceeds smoothly at room temperature and shows broad functional-group tolerance. A radical process is proposed for this transformation. The coupling of aryldiazonium tetrafluoroborates, DABCO×(SO2)2, and hydrazines under metal-free conditions leads to the formation of aryl N-aminosulfonamides. The reaction proceeds under mild reaction conditions, is fast, has a broad substrate scope, and gives the products in high yiels (21 examples). A plausible mechanism that involves a radical process is also proposed. Copyright

In the current study, two new series of N-alkyl-N-(piperidin-1-yl) benzenesulfonamide (3a-f) and N-aryl substitued 2-[(phenylsulfonyl)- (piperidin-1-yl)amino]acetamide (5a-c) were synthesized and enzyme inhibiting activity was screened for all these chemi
