title: Boc groups as protectors and directors for Ir-catalyzed C-H borylation of heterocycles.
abstract: Ir-catalyzed C-H borylation is found to be compatible with Boc protecting groups. Thus, pyrroles, indoles, and azaindoles can be selectively functionalized at C-H positions beta to N. The Boc group can be removed on thermolysis or left intact during subsequent transformations.
