well-defined homoallylic thioethers 3 are synthesized via Lewis acid promoted condensation reaction between chiral organosilane reagents 2 and in situ generated thionium ions. The stereochemical course of the reaction is consistent with earlier reports concerning crotylsilations of oxonium ions.
通过路易斯酸促进的手性有机硅烷试剂2与原位生成的硫鎓离子之间的缩合反应合成了立体化学定义明确的均烯丙基硫醚3。该反应的立体化学过程与关于氧鎓离子的巴豆基硅烷基化的早期报道一致。
