An external oxidant free Ru(II)-catalyzed C–H activation followed by an intermolecular annulation between oximes and sulfoxoniumylides has been developed. This transformation proceeds smoothly with a broad range of substrates, affording a series of isoquinoline derivatives in moderate to good yields. This protocol was successfully applied to the synthesis of moxaverine.
开发了一种无外部氧化剂的 Ru( II ) 催化的 C-H 活化,然后在肟和亚砜叶立德之间发生分子间成环。这种转化可以在多种底物下顺利进行,以中等至良好的产率提供一系列异喹啉衍生物。该方案成功应用于莫沙维林的合成。
