Using aniline derivatives containing lactone structure and styrenes as the starting materials, a series of lactone substituted quinolines were constructed efficiently by oxidative Povarov reaction, promoted by radical cation salt. This reaction provides a new method to achieve the construction of functionalized quinoline skeletons. The mechanistic study reveales that the oxidation of the saturated C-H bond is mediated by free radical intermediate.
Key words: radical cation salt, C-H activation, Povarov reaction, quinoline, lactone
