摘 要:An unprecedented difluorocarbene-mediated C-O bond cleavage of cyclic ethers for the construction of difluoromethyl ethers is herein disclosed.This protocol is distinguished by its mild conditions,high efficiency,and wide substrate scope,which can tolerate both sensitive functional groups such as the hydroxyl group,olefin and C-C triple bonds,as well as complex molecules.It thus demonstrates excellent chemoselectivities and great potential for late-stage modification of pharmaceutical compounds and natural products.It is worth noting that this method not only introduces fluorine atoms into the final molecules,but it can also effectively form an ester or ether linkage.
