An unprecedented approach of metal-free C(sp2)-N bond formation via deacetylation/intramolecular aryl migration is demonstrated with novel N-sulfonamide substituted diaryliodonium salts. The reaction provides a variety of ortho-iodo N-aryl sulf

We report herein an atroposelective N-acylation of sulfonamides using a commercially available isothiourea catalyst, (S)-HBTM, with a simple procedure. The N-sulfonyl anilide products can be obtained in good to high enantiopurity, which represents a new axially chiral scaffold. The application of the product as a chiral iodine catalyst is also demonstrated for the asymmetric α-oxytosylation of propiophenone.
Synthesis of 11a- N -Arylsulfonyl-5-carbapterocarpans (Tetrahydro-5 H -benzo[ a ]carbazoles) by Azaarylation of Dihydronaphthalenes with o -Iodo- N -(Arylsulfonyl)anilines in Poly(ethylene glycol)

11a-N-Arylsulfonyl-5-carbapterocarpans (tetrahydro-5H-benzo[a]carbazoles) were synthesized by palladium-catalyzed azaarylation of dihydronaphthalenes with o-iodo-N-(arylsulfonyl)anilines in poly(ethylene glycol) (PEG-400). Better chemical yields (moderate
