Synthesis of para-cyclopentylanilines from ortho-(cyclopent-1′-enyl)anilines

ortho - para-Migration of the cyclopentenyl fragment in 2-(cyclopent-1′-enyl)aniline or 2-(cyclopent-1′-enyl)-6-methylaniline hydrochloride at 200 °C gives 4-cyclopentylaniline or 4-cyclopentyl-2-methylaniline.

Synthesis of 2-Quinolinones via a Hypervalent Iodine(III)-Mediated Intramolecular Decarboxylative Heck-Type Reaction at Room Temperature

A hypervalent iodine(III)-mediated intramolecular decarboxylative Heck-type reaction of 2-vinyl-phenyl oxamic acids has been developed. The unique ring-strain-enabled radical decarboxylation mechanism is preliminarily revealed. This protocol features metal-free reaction conditions and operational simplicity, allowing the lactamization of 2-vinylanilines using a readily accessible carbonyl source and the synthesis of various 2-quinolinones with excellent chemoselectivity at room temperature.

Borane-Catalyzed Synthesis of Quinolines Bearing Tetrasubstituted Stereocenters by Hydride Abstraction-Induced Electrocyclization

The borane-catalyzed synthesis of quinoline derivatives bearing tetrasubstituted stereocenters from vinyl anilines has been developed. Mechanistic studies and quantum-mechanical investigations support the hydride abstraction/electrocyclization/hydride add

The conversion of benzothiazines to 2-alkenyl anilines

Upon treatment with excess potassium dimsylate in DMSO benzothiazines 1a-1j undergo an elimination of the sulfoximine functional group to give 2-alkenylsulfinanilides nonstereoselectively in good to excellent yield. These are easily converted to the corre
