A regioselective and nucleophilic halogenation of electron-rich amidophenols was realized in the presence of Fe(III) reagents and amido-directing groups. Halides could be sequentially introduced to specific positions to form mono-, di- and mixed di- halogenated amidophenols. Furthermore, this protocol provides new methods for the syntheses of IKK2 inhibitor (IMD-0354), muscle relaxant (Chlorzoxazone) and related derivatives.

Unprecedented enantioselective intramolecular Heck carbonylation reactions of arenediazonium salts were enabled by a chiral N,N ligand. This reaction constitutes the first enantioselective Heck carbonylation that proceeds through migratory insertion followed by CO insertion. The enantioenriched functionalized dihydrobenzofurans were obtained in good to high yields and enantiomeric ratios of up to 98:2 under mild and operationally simple reaction conditions.

Cyclization reactions of 2-aminophenols with β-diketones catalyzed by a combination of Br?nsted acid and CuI are presented. Various 2-substituted benzoxazoles were obtained through these reactions. Different substituents such as methyl, chloro, bromo, nitro, and methoxy on 2-aminophenol are tolerated under the optimized reaction conditions.
