of tricarbonyl-η6-(1-tri-isopropyisilylindote)chromium(0) and η6-(1 -tri-isopropylsilyl-3-methoxymethylindole)tricarbonylchromium(0) followed by an electrophilic quench produced a series of 4-substituted indole complexes. For the 4-acyl, -allyl and -alkenyl analogues, transmetallation of the lithio- species to the corresponding cupro- complexes and reaction with the appropriate halides (in the alkenyl
三羰基-η的锂化6(1-三isopropyisilylindote)铬(0)和η - 6 -随后的亲电骤冷(1 -三isopropylsilyl -3- methoxymethylindole)tricarbonylchromium(0)生产的系列4-取代的吲哚的复合体。对于4-酰基,-烯丙基和-烯基类似物,硫硫基物种的金属转移成相应的铜配合物,并与适当的卤化物反应(在烯基情况下为钯催化)总共有4-替代品。将复合物解复合和去甲硅烷基化以产生中等至良好的总产率的4-取代的吲哚。
