Abstract:

Here reported is an intramolecular nucleophilic substitution reaction of aryl-thianthrenium salts, which conducts the selective cleavage of C—O and C—S chemical bonds and represents a novel conversion of aryl-thianthreniums, rapidly assembling the highly conjugated tribenzo-thioester compounds. This developed methodology is charactered by excellent functional group tolerance, good productivities, and metal-free trait. This conversion delivers 23 examples of structurally innovative nine-membered thioethers, which puts forward an alternative synthesizing route for the widely used crown ethers.

Key words: Arylthianthreniums, C—S bond cleavage, Benzo-thioester
