An easily available iron catalyst was developed to accomplish the CH functionalization of indoles with α-aryl-α-diazoesters in high yields under mild conditions. The asymmetric CH functionalization of indoles was also realized by using iron complexes of chiral spiro bisoxazolines with up to 78% ee.
