Copper-Catalyzed Aminoarylation of Alkenes via Aminyl Radical Addition and Aryl Migration

We describe a new strategy for aminoarylation of alkenes by copper-catalyzed smiles rearrangement using O-benzoylhydroxylamines as the amine reagent. This method affords various β-amino amide derivatives possessing a quaternary carbon center with wide functional group tolerance and high regioselectivity. The mechanistic studies indicate that the transformation can involve aminyl radical intermediates under acid-free condition.

Sequential C-S and S-N Coupling Approach to Sulfonamides

A one-pot three-component reaction involving nitroarenes, (hetero)arylboronic acids, and potassium pyrosulfite leading to sulfonamides was described. A broad range of sulfonamides bearing different reactive functional groups were obtained in good to excellent yields through sequential C-S and S-N coupling that does not require metal catalysts.

Synthesis of: N -arylsulfonamides via Fe-promoted reaction of sulfonyl halides with nitroarenes in an aqueous medium

A fascinating Fe-promoted protocol for the synthesis of N-arylsulfonamides has been developed. Starting from commercially available nitroarenes and sulfonyl chlorides, moderate to excellent yields of the corresponding N-arylsulfonamides can be obtained. In particular, Fe dust serves as the sole reductant in the transformation and it can be easily performed on a large scale.

Palladium-catalyzed desulfitative arylation of sulfonamides with sodium arylsulfinates

A Pd(II)-catalyzed desulfitative arylation protocol between sulfonamides and sodium arylsulfinates was herein reported. The direct arylation reaction was successfully achieved by a Pd(II)/Ag(I)-mediated system without participation of any external ligands with a release of SO2. And different N-aryl sulfonamides were obtained readily in up to 86% yields, exhibiting good functional groups tolerance (25 examples).

Palladium-catalyzed N-arylsulfonamide formation from arylsulfonyl hydrazides and nitroarenes

A palladium-catalyzed construction for N-arylsulfonamide from nitroarenes and arylsulfonyl hydrazides is developed. In this protocol, abundant and stable nitroarenes serve as the nitrogen sources by in situ reduction reaction of hydrogen released from arylsulfonyl hydrazides. No external oxidants or reductants are needed for this kind of transformation.

Palladium-catalyzed arylation of aryl sulfonamides with cyclohexanones

Pd-catalyzed intermolecular aerobic dehydrogenative aromatizations have been developed for the arylation of aryl sulfonamides with cyclohexanones. Various N-aryl sulfonamides were selectively obtained in good yields using molecular oxygen as oxidant. The reaction tolerated a wide range of functionalities.

Novel arylsulfoanilide-oxindole hybrid as an anticancer agent that inhibits translation initiation

Structure-activity relationship studies of substituted arylsulfoanilides as antiproliferatives, which are mediated by the partial depletion of intracellular Ca2+ stores, resulted in the identification of compounds with micromolar activity against lung cancer cells in a growth inhibition assay. Incorporating the substitution pattern of the best arylsulfoanilides onto the 3-phenyloxindole scaffold resulted in a potent arylsulfoanilide-oxindole hybrid, 27. Compound 27 inhibits cancer cell growth by partial depletion of intracellular Ca2+ stores and phosphorylation of eIF2α.
