A rhodium(III)-catalyzed protocol for the synthesis of pyrrolo[1,2-a]quinolines through intramolecular annulation of o-alkynyl amino aromatic ketones and subsequent aromatization is reported. This transformation builds the pyrrole and quinoline moieties of the pyrrolo[1,2-a]quinoline in one pot and achieves a flexible introduction of different substituent groups at 4- and 5-positions on products that
报告了一种通过邻炔基氨基芳香酮的分子内环化和随后的芳构化合成吡咯并[1,2- a ]喹啉的铑 (III) 催化方案。这种转化在一锅中构建了吡咯并[1,2- a ]喹啉的吡咯和喹啉部分,实现了在其他方法难以制备的产物上灵活引入4-和5-位不同取代基。反应在克级上顺利进行,产品适合下游合成操作。
