Abstract

An efficient one-pot synthesis of N-aryl-substituted heterocycles by a Cu-catalyzed two-fold C–N bond formation is reported. This strategy involves a Cu I -catalyzed C–N bond-forming reaction between azoles and electron-deficient bromopyridines followed by an intramolecular sp 2 C–H amination. One of the products thus formed has been successfully used as a ligand for the synthesis of a Pd complex.
