A highly efficient Rh‐catalyzed regioselective C8−H acylmethylation of quinoline N‐oxides with sulfoxonium ylides using N‐oxide as the directing group under air atmosphere has been developed. This transformation has the generality of a broad scope of substrates, avoids external oxidants, and provides an efficient protocol to C8−H acylmethylated quinolines.

Rh（III）催化喹啉N氧化物的选择性C8-H酰基甲基化

已经开发出一种高效的Rh催化的喹啉N-氧化物的区域选择性C8-H酰基甲基化，其在空气气氛下以N-氧化物为导向基团与sulf基亚砜形成。这种转化具有广泛范围的底物通用性，避免了外部氧化剂，并为C8-H酰基甲基化喹啉提供了有效的方案。
