subsequent oxidation to the rare indolizine-5,8-diones is described. When the rearrangement is carried out in the presence of DMAD the indolizines are trapped in an 8+2 cycloaddition to give [3.2.2]cyclazines.
描述了热诱导的4-(1-吡咯基)-4-三甲基甲硅烷氧基环丁烯酮的环膨胀成5-羟基-8-三甲基甲硅烷氧基吲哚并随后氧化成稀有的吲哚嗪-5,8-二酮。当在DMAD存在下进行重排时,吲哚嗪被困在8 + 2环加成反应中,生成[3.2.2]环嗪。
