Dearomative Iodocyclization of N -( o -Alkynyl)aryl Isoindole.

We present a dearomative iodocyclization of N- ( o -alkynyl)aryl isoindole here, which affords various biologically active benzoindoleazine skeletons containing alkenyl iodine. The products can further undergo cycloaddition or coupling reactions to afford a series of highly functionalized N-fused polycyclic scaffolds.
