Polycyclic heterocycles containing indoles or pyrroles are interesting structural motifs present in a number of natural and unnatural products displaying a wide variety of biological and pharmacological properties. [¹] Construction of these polycyclic heterocycles, in particular those containing an aryl-N-indole or N-pyrrole bond, usually requires lengthy multiple-step syntheses involving transition-metal-catalyzed reactions. [²] Hence, the development of new, mild, and ...
