Based on Claisen rearrangement, the double bond isomerization of O-allyl function together with the formation of O-vinyl function in one pot, and ring-closing metathesis (RCM), various phenols were transformed into various benzofurans in good yields.
基于克莱森重排,O-烯丙基官能团的双键异构化以及O-乙烯基官能团的一锅形成,以及闭环复分解(RCM),各种酚类以良好的收率转化为各种苯并呋喃。
