title: Silver-catalyzed synthesis of 4-substituted benzofurans via a cascade oxidative coupling-annulation protocol.
abstract: A facile synthesis of 4-indole benzofurans from the one-pot reaction of 4-alkyl-2-ynylphenols and indoles via a hypervalent iodine-induced oxidative dearomatization, a silver-catalyzed cascade Michael addition-annulation, and an aromatization is reported.
