Functionalization of α-C(sp3)?H Bonds in Amides Using Radical Translocating Arylating Groups
Radhoff, Niklas,Studer, Armido
, p. 3561 - 3565 (2021/01/04)
α-C?H arylation of N-alkylamides using 2-iodoarylsulfonyl radical translocating arylating (RTA) groups is reported. The method allows the construction of α-quaternary carbon centers in amides. Various mono- and disubstituted RTA-groups are applied to the arylation of primary, secondary, and tertiary α-C(sp3)?H-bonds. These radical transformations proceed in good to excellent yields and the cascades comprise a 1,6-hydrogen atom transfer, followed by a 1,4-aryl migration with subsequent SO2 extrusion.
One-pot, Pd/Cu-catalysed synthesis of alkynyl-substituted 3-ylidene-dihydrobenzo[d]isothiazole 1,1-dioxides

, p. 789 - 793 (2017/03/31)
Enyne-substituted benzoisothiazole derivatives have been synthesised under one-pot, operationally simple conditions using 2-iodo-N-(trimethylsilylethynyl)benzenesulfonamides and terminal alkynes as starting materials and a palladium–copper-based catalytic system. The structure of these heterocycles has been demonstrated by NMR spectroscopy and confirmed by X-ray crystallographic analysis. A plausible reaction mechanism has been proposed.

A group of regioisomeric phenylethynylbenzenesulfonamides possessing a COX-2 SO2NH2 pharmacophore at the para-, meta- or ortho-position of the C-1 phenyl ring, in conjunction with a C-2 substituted-phenyl (H, OMe, OH, Me, F) group, w
