A new bicyclic sulfonamide derivative, N-(1-(bromomethyl)-7,7-dimethylbicyclo[2.2.1]heptan-2-yl)benzenesulfonamide, was synthesized in the reaction of benzenesulfonamide and camphene presence N-bromosuccinimide acetonitrile. The proposed mechanism investigated involves Wagner–Meerwein rearrangement stage. 3-(Bromomethylene)-2,2-dimethylbicyclo[2.2.1]heptane isolated as a minor product. products...

We developed an organophotoredox-catalyzed reaction for N-alkylation of sulfonamides with aliphatic carboxylic acid-derived redox active esters as alkylating reagents. Under mild and transition metal-free conditions, a series functionalized N-alkylated were prepared. This protocol also enabled the functionalization pharmaceutical drugs bearing sulfonamide or acid moiety. radical-mediated proces...

A new, versatile and direct Pd-mediated method involving intramolecular cyclization of N-(2-iodoaryl)-N-(1-alkyl-1H-indol-2-yl)alkane/arene/heteroarene sulfonamide has been developed leading to a diverse and unique class of indolo[2,3-b]indoles for the potential inhibition of sirtuins.

A series of novel sulfonamide isoxazolo[5,4-b]pyridines were synthesized. The substrates for their synthesis were 3-aminoisoxazolo[5,4-b]pyridine and selected aryl sulfonic chlorides, chlorosulfonic acid and selected amines. Reactions were carried out using the classical and microwave methods. Selected compounds were tested towards antibacterial and antiproliferative activity. The structure of ...

In the title compound, C(14)H(20)N(2)O(2)S, the sulfonamide O atoms lie to one side of the benzene ring and the amino-bicyclo-hepta-nyl to the other side [C(ar)-S-N-C torsion angle = -57.93 (11)°; ar = aromatic]. An intra-molecular N-H⋯N hydrogen bond is formed. In the crystal, a supra-molecular chain is formed along the b axis via N-H⋯O and N-H⋯N hydrogen bonds.

De-protected arabino N-glycosyl sulfamides, sulfonamides and sulfamates were found to mutarotate and convert from the furanose to the thermodynamically more stable pyranose form in aqueous solution. The presence of a strongly electron withdrawing group in the alkyl chain stopped mutarotation and furanose/pyranose equilibration, allowing the isolation of the first unprotected furanose N-glycosyl...
