formation through 5-endo halocyclization of unsaturated amides, direct C–H oxidative functionalization and N-acyliminium cyclization is described. A range of β-iodo-pyrrolidinones can be efficiently synthesized using this method, making it an excellent approach for constructing natural products containing pyrrolidinones. Besides, we have developed convenient alternative routes for the synthesis of pyrroloisoquinolines
描述了通过不饱和酰胺的5-内卤代环化,直接的C–H氧化功能化和N-酰基环化形成吡咯并异喹啉。使用此方法可以有效地合成各种β-碘-吡咯烷酮,使其成为构建含有吡咯烷酮的天然产物的极佳方法。此外,我们已经开发了方便的替代路线,可在两个分开的步骤或一个罐中合成吡咯并异喹啉。
