Halogenated arenes are important structural motifs commonly found in biologically active molecules and used for a variety of transformations in organic synthesis. Herein, we report the mono-protected l-amino acid (l-MPAA) accelerated iridium(III)-catalyzed halogenation of (hetero)anilides at room temperature. This reaction constitutes the first example of an iridium(III)/l-MPAA-catalyzed general halogenation of (hetero)arenes through C(sp2 )-H activation. Furthermore, we demonstrate the potential utility of our method through its use in the synthesis of a quinolone derivative.
Keywords: C−H activation; anilides; halogenation; iridium; l-MPAA.
