The highly efficient and stereo-specific synthesis of the enantioenriched versatile building blocks—namely, β-vinyltryptamines—by rhodium-catalyzed allylic substitutions of vinylaziridines and indoles is presented. Besides indoles, pyrroles can also serve as competent carbon nucleophiles in the current reaction, which is different from the previous works. To demonstrate the synthetic utility of our
提出了通过铑催化的乙烯基氮丙啶和吲哚的烯丙基取代,对映体富集的通用结构单元(即,β-乙烯基色胺)的高效立体定向合成。除吲哚外,吡咯还可以在当前反应中充当有效的碳亲核试剂,这与以前的工作不同。为了证明我们方法的合成效用,在高效反应序列中合成了多达11种天然产物和药学上相关的手性吲哚支架。值得注意的是,也报道了有效的受约束的MS-245类似物与nNOS和5-HT 1B / 1D受体抑制剂的不对称形式合成。
