| Abstract: | A metal-free oxidative arene/alkene annulation-aromatization has been realized, which enables efficient synthesis of 2-arylnaphtho2,1-b]furans from readily available terminal aryl alkenes and 2-naphthols. Mechanistic study suggests that this reaction proceeds via free-radical initiated tandem cyclization, dehydrogenative rearomatization and aromatization. |
