  Organocatalytic Arylation of 3-Indolylmethanols via Chemo- and Regiospecific C6-Functionalization of Indoles

  摘要：

  An organocatalytic arylation of 3-indolylmethanols has been established via chemo- and regiospecific C6-functionalization of 2,3-disubstituted indoles, leading to the production of bisindolyloxindoles containing an all-carbon quaternary stereocenter in high yields (up to 99% yield). This reaction not only represents the first catalytic arylation of 3-indolylmethanols using 2,3-disubstituted indoles as aromatic nucleophiles but also serves as a good example of direct catalytic C6-functionalization of indoles, which have been scarcely investigated. Besides, this approach also provides an efficient method to access a biologically important 3,3'-disubstituted oxindole framework and a 3',6-linked bisindole skeleton. Furthermore, the investigation of the activation mode suggested that the dual activation of an ion pair and H-bond between the substrates and the catalyst cooperatively contributed to the success of the reaction.

  Chiral imidodiphosphoric acid-catalysed asymmetric functionalization of 3-hydroxy bisindoles was established. Sulfur-containing groups could be successfully introduced into isatin frameworks using commercially available thiols. The transformation was compatible with substrates bearing distinct substituents, both aromatic and aliphatic thiols were amenable to afford the desired products. A total of
