A Rh(I)-catalyzed intermolecular cyclization between isocyanates and benzocyclobutenols leading to isoquinolin-1(2H)-ones through selective cleavage of a C–C bond has been realized. Exploiting the same strategy, we developed a Rh(I)-catalyzed three-component reaction of benzocyclobutenols, isonitriles, and sulfonyl azides to access isoquinolin-1(2H)-imines. These procedures provide unique and expeditious

Catalytic construction of oxindoles bearing all-carbon-quaternary centers attracts wide attention from the synthetic chemistry community. Herein, we report a palladium-catalyzed sequential Heck coupling/C–C bond activation of aryl halide-tethered alkenes with benzocyclobutenols affording a series of oxindole-derived compounds in good to excellent yields, as well as the preliminary enantioselectivity

rhodium(III)-catalyzed regio- and chemoselective amidation of benzocyclobutenols has been realized using dioxazolone as the amidating reagent to afford three classes of C–N-coupled products via β-carbon elimination of the benzocyclobutenol. The Co(III)-catalyzed coupling initially afforded an isolable o-(N-acylamino)arylmethyl ketone, which could further cyclize to the corresponding indole derivatives under
