Metal-Free One-Pot Access to Benzofuran Building Blocks Toward Efficient Narrowband Blue-Cyan Emitters.
A metal-free amino-group-directed regioselective cyclization from α-diketone compounds and diarylamines is reported for the synthesis of benzofuran derivatives. The transformation proceeds through sequential intermolecular and intramolecular Friedel-Crafts-type processes under acidic conditions, enabling one-pot constr...
