Switching the regioselectivity via indium(III) and gold(I) catalysis: a post-Ugi intramolecular hydroarylation to azepino- and azocino-[c,d]indolones

A post-Ugi indium(III)- and gold(I)-mediated regioselective intramolecular hydroarylation for the synthesis of azepino- and azocino[c,d]indolones is described.
