We have developed a novel one pot synthesis of 4-chloroquinolin-2-ylamines via Smiles rearrangement under milder condition. The key transformation involves O-alkylation of 4-chloro-1H-quinolin-2-ones with chloroacetamide followed by Smiles rearrangement. The scope of this methodology is further extended to the synthesis of 4-chloroquinolin-2-ylmethylamines and 2-(4-chloroquinolin-2-ylamino)ethanols
我们已经开发了一种在温和条件下通过Smiles重排合成4-氯喹啉-2-基胺的新型一锅法。关键转化涉及用氯乙酰胺对4-氯-1 H-喹啉-2-酮进行O-烷基化,然后进行Smiles重排。该方法的范围进一步扩展至4-氯喹啉-2-基甲胺和2-(4-氯喹啉-2-基氨基)乙醇的合成。该方法提供了2-氨基-4-氯喹啉的良好产率。
