3-Aroylindoles have been prepared via copper-catalyzed cyclization of N-(2-iodoaryl)enaminones, readily available from 2-iodoanilines and α,β-ynones. The reaction tolerates a variety of useful functionalities including ether, keto, cyano, bromo, and chloro substituents. This indole synthesis can also be carried out from 2-iodoanilines and α,β-ynones through a sequential process that omits the isolation of enaminone intermediates.
3-Aroylindoles 是通过铜催化 N-(2-碘芳基)烯丙酮环化反应制备的,这种环化反应很容易从 2-碘苯胺和 δ,δ-炔酮中获得。该反应可容忍多种有用的官能团,包括醚基、酮基、氰基、溴基和氯基取代基。这种吲哚合成法也可以通过省略烯酮中间体的分离过程,从 2-碘苯胺和 δ,δ-炔酮中依次进行。
