Synthesis of cyclic sulfides by intramolecular ring opening of epoxides by thiolates generated by nickel complex catalyzed electroreduction of thioacetates
The nickel(II) complex catalyzed electroreduction of thioacetates attached to epoxides provided five- to seven-membered cyclic sulfides in good to high yields by regioselective ring opening of epoxides followed by thioheterocyclization. (C) 2000 Elsevier Science Ltd. All rights reserved.
