Switching the regioselectivity via indium(iii) and gold(i) catalysis: a post-Ugi intramolecular hydroarylation to azepino- and azocino-[c,d]indolones†
Abstract
A post-Ugi indium(III)- and gold(I)-mediated regioselective intramolecular hydroarylation for the synthesis of azepino- and azocino-[c,d]indolones is described.
