This methodology provides facile access to butenolide tethered homotryptamines in good to excellent yields under operationally simple conditions and features a broad substrate scope. Overall, the reaction sequence involves the formation of three new bonds (two C–C and one C–O) in a nucleophilic cascade manner. Additionally, an intramolecular rearrangement of these derivatives to thermodynamically more
已开发出一种高效的 Rh(II) 催化吲哚与 1,2,3-三唑基丙炔酸酯的脱氮反应。这种方法可以在操作简单的条件下轻松获得丁烯内酯系留的同色胺,并具有广泛的底物范围。总的来说,反应序列涉及以亲核级联方式形成三个新键(两个 C-C 和一个 C-O)。此外,还证明了这些衍生物的分子内重排为热力学更稳定的丁烯内酯。
