A metal-free oxidative arene/alkene annulation-aromatization has been realized, which enables efficient synthesis of 2-arylnaphtho[2,1-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.

BF3-末端芳基烯烃催化萘的氧化串联环化-芳构化

已经实现了无金属的氧化芳烃/烯烃环化-芳构化，其能够从容易获得的末端芳基烯烃和2-萘酚有效地合成2-芳基萘[2，1-b]呋喃。机理研究表明，该反应是通过自由基引发的串联环化，脱氢重新芳构化和芳构化来进行的。
