a diverse range of arylamidines from a novel cascade reaction of in situ generated nitrile oxides, sulfonyl azides, terminal alkynes, and water by [3 + 2] cycloaddition and ring opening sequence was developed. The use of aryl oxime chlorides as the carbon source of the amidine group and the addition of water proved to be critical for the reaction. Moreover, terminal alkynes, which can lead to high yields
终端炔烃辅助方案可通过[3 + 2]环加成和开环顺序一锅法生成原位生成的腈氧化物,磺酰叠氮化物,终端炔烃和水的新型级联反应,从而一锅式形成多种芳基胺。发达。使用芳基肟氯化物作为am基的碳源并添加水对于反应至关重要。而且,末端炔烃可以通过使用较少量而导致高产率的产物,可以在反应中起催化作用。研究了更广泛的基材。
