New synthetic approaches for the synthesis of indoloquinolines and carbocycle-fused quinolines have been developed employing alkynylketone substrates. These synthetic transformations involved the application of N2-extrusion of azido complexes as a key step to generate carbodiimidium ion and nitrilium ion in situ, which further cyclized intramolecularly with alkyne via a domino process to provide indoloquinolines
已经使用炔基酮底物开发了用于合成吲哚喹啉和碳环稠合喹啉的新的合成方法。这些合成转化涉及将N 2-叠氮基络合物的挤出应用作为原位生成碳二亚胺离子和腈离子的关键步骤,然后通过多米诺过程与炔烃分子内进一步环化,以分别提供吲哚喹啉和碳环稠合喹啉。中等至良好的产量。
