Reactions in Organic Synthesis Abstract Catalyzed by the complex generated in situ from iridium and the chiral ferrocene ligand, tert-butyl (4-oxo-4-arylbutyl)carbamate substrates were deprotected and then reductively cyclised to form 2-substituted arylpyrrolidines in a one-pot manner, in which the intramolecular reductive amination was the key step. A range of chiral 2-substituted arylpyrrolidines were
作为有机合成中的特殊主题胺化反应的一部分发布 抽象的 通过由铱和手性二茂铁配体原位生成的配合物催化,叔丁基(4-氧代-4-芳基丁基)氨基甲酸酯底物被脱保护,然后被还原环化,以一锅方式形成2-取代的芳基吡咯烷。分子内还原胺化是关键步骤。合成了一系列手性2-取代的芳基吡咯烷,产率高达98%,ee高达92%。 通过由铱和手性二茂铁配体原位生成的配合物催化,叔丁基(4-氧代-4-芳基丁基)氨基甲酸酯底物被脱保护,然后被还原环化,以一锅方式形成2-取代的芳基吡咯烷。分子内还原胺化是关键步骤。合成了一系列手性2-取代的芳基吡咯烷,产率高达98%,ee高达92%。
