摘要：

Indole-carboxylates are N-arylated with 2-bromopyridines using stoichiometric copper(II) oxide/potassium carbonate to give various N-(2-pyridyl)-substituted indole-2-carboxylates and with bromobenzenes using stoichiometric copper(I) iodide/N,N'-dimethylethylenediamine to give various N-(substituted phenyl)-substituted indole-2-carboxylates. These results expand the scope of metal-catalyzed N-arylation using heterocyclic amines with steric bulk and weak nucleophilicity.
