A series of dihydro-benzoimidazo-thiazine derivatives displaying exclusive diastereoselectivity has been synthesized proficiently via external chemical oxidant and metal-free selenocyclization methodology. This mild electro-oxidative protocol operates in an undivided electrochemical cell at ambient temperature under air, exhibiting decent functional group tolerance and excellent yields.
通过外部化学氧化剂和无金属硒环化方法,已经合成了一系列具有独特非对映选择性的二氢苯并咪唑并噻嗪衍生物。这种温和的电氧化方案在空气中的环境温度下在未分开的电化学电池中运行,表现出良好的官能团耐受性和出色的产率。
