Abstract

Herein, we have developed a novel and simple protocol to realize the C–H bond functionalization/dearomatization of naphthols and phenols with ortho-alkynylaryl-α-diazoesters under gold(I) catalysis. In this protocol, various spirocyclic molecules could be obtained in good yields with excellent chemo- and regio-selectivity and moderate to good diastereoselectivity.
