A variety of functionalities, including the whole range of halogen substituents, are tolerated in the title reaction, an intramolecular approach for the construction of a multisubstituted indole skeleton from readily available enaminones (see scheme; phen=1,10‐phenanthroline). The indole products are also prepared directly in high yield from α,β‐ynones and primary amines.
标题反应具有多种功能,包括卤素取代基的整个范围,这是一种分子内方法,可从容易获得的烯胺酮中构建多取代的
吲哚骨架(参见方案; phen = 1,10-phenothroline)。
吲哚产物还可以直接由α,β-炔酮和
伯胺直接制备得到。
