Methylthiolation for Electron‐Rich Heteroarenes with DMSO‐TsCl
DMSO‐TsCl is developed for methylthiolation of various heteroarenes including pyrroles, furans, thiophenes and indoles under facile conditions. This protocol features scalable, general applicability of substrates and moderate to excellent yields. An acceptable mechanism is proposed, two of the key intermediates of proposed mechanism are detected by HRMS. Further applications of this method were also

Treatment of the endo-thioester group substituted norbornenes 3a-3d with iodine in aqueous tetrahydrofuran at 25 °C gave the novel methylthio group rearranged lactonization products 4a-4d in 80% yields; iodolactonization reaction of 9 was applied to the synthesis of noveldiacetaltrioxa-cage compound 13.
