preparation of various N-(o-halophenyl)enecarbamates that served as useful precursors for subsequent 5-endo-trig Heck or 5-endo-trig aryl radical cyclizations to furnish 2-substitutedindoles or indolines, respectively. Furthermore, a one-pot Suzuki−Miyaura coupling−cyclization cascade starting from enol phosphates has been developed, which was successfully applied to the efficient synthesis of an in
