A concise and regioselective preparation of 2-heteroarylmethylene decorated N-arylpyrroles is described through a metal-free Mannich/Wittig/hydroamination sequence followed by isomerization of the N-arylpyrrolidine adducts. Furthermore, the C–H regioselective oxidation of these substrates is demonstrated, extending the molecular diversity and versatility of these scaffolds.
本文描述了一种简洁、区域选择性的制备2-杂环芳基甲烯修饰的N-芳基吡咯的方法,该方法通过无金属的Mannich/Wittig/氢胺化序列,然后通过N-芳基吡咯啉加合物的异构化来实现。此外,还演示了这些底物的C-H区域选择性氧化,扩展了这些支架的分子多样性和多功能性。
