We have described the application of iron(III) chloride and diorganyl diselenides as cooperative partners in the cyclization of (2-aminoaryl)-2-ynols for the regioselective synthesis of 3-organoseleno quinolines. The optimized reaction conditions were applied to (2-aminoaryl)-2-ynols that contain a wide range of functional groups, including electron-rich and electron-poor substituents. The reaction
我们已经描述了氯化铁 (III) 和二有机二硒化物作为合作伙伴在(2-氨基芳基)-2-炔醇的环化中的应用,用于区域选择性合成 3-有机硒基喹啉。将优化的反应条件应用于 (2-氨基芳基)-2-炔醇,其包含多种官能团,包括富电子和缺电子取代基。该反应显示六元喹啉产物的区域选择性,这些产物是通过 6-endo-dig 闭环形成的,而不是用于形成吲哚产物的 5-exo-dig 过程。此外,我们还发现(2-氨基芳基)-2-炔醇和催化量的氯化铁(III),在没有二有机二硒化物的情况下,提供了相应的喹啉衍生物,在 3-位没有有机硒基部分。
