Tetrahydrobenz[cd]indole derivatives (51–54) were synthesized from 4-iodo-3-(2′-nitroethyl)indole (10) via palladium-catalysed coupling with acetylenes followed by a thiol addition, an oxidation and an intramolecular Michael-addition.
由4-碘-3-(2'-硝基乙基)吲哚(10)经钯催化与乙炔的偶合,硫醇加成,氧化和分子内Michael-合成了四氢苯并[ cd ]吲哚衍生物(51-54)。添加。
