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.).

A three-component reaction of triethoxysilanes, sulfur dioxide, and hydrazines catalyzed by copper(II) acetate is reported, leading to N-aminosulfonamides in good yields. Not only triethoxy(aryl)silanes but also triethoxy(alkyl)silanes are compatible during the process of insertion of sulfur dioxide. Additionally, diethoxydiarylsilanes are suitable under the conditions as well.

A facile route to aryl N-aminosulfonamides under mild conditions is provided. The reaction of aromatic amines (including heteroaromatic amines), sulfur dioxide, and hydrazines proceeds efficiently with good functional group tolerance. The in situ generated diazonium ion is involved in the aminosulfonylation process. This journal is the Partner Organisations 2014.

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
