alkyl–aryl coupling reaction between sulfones and arylboron compounds has remained a challenge. We report the first iron-catalyzed radical difluoroalkylation of arylborates with N-heteroaryl sulfones. The coordination between the iron catalyst and the nitrogen atom of N-heteroaryl sulfones was identified to be important in overcoming the reductionpotentiallimitation of sulfones in the intermolecular single-electron-transfer

The invention provides modulators for the orphan nuclear receptor RORy and methods for treating RORy mediated diseases by administering these novel RORy modulators to a human or a mammal in need thereof. Specifically, the present invention provides carboxamide or sulfonamide containing cyclic compounds of Formula (1), (1'), (100), (100'), (200) and (200') and the enantiomers, diastereomers, tautomers, /V-oxides, solvates and pharmaceutically acceptable salts thereof.

xyl]thioureas, with hetaryl representing either 4,6-dimethyl-1,3-diazin-2-yl, 4,6-diisopropyl-1,3,5-triazin-2-yl, or 4,6-di-tert-butyl-1,3,5-triazin-2-yl groups. These compounds are structural analogs of Takemotos’s chiral thioureaorganocatalysts (1-[3,5-bis(trifluoromethyl)phenyl]-3-[(1S,2S)-2-(dimethylamino)cyclohexyl]thiourea) with an aza-aryl instead of the 3,5-bis(trifluoromethyl)phenyl group
