Regio- and stereo-selective synthesis of β-phenylthio enamides via intramolecular 1,2-thiol migration†
Abstract
An efficient and novel method for the synthesis of β-phenylthio enamides via intramolecular 1,2-thiol migration has been developed. The preliminary experimental and computational studies suggest an unconventional mechanism involving the additive Pummerer reaction, 1,2-thiol migration, nucleophilic addition, and a syn-elimination process.
