  Iodine-Mediated C–H Functionalization of sp, sp², and sp³ Carbon: A Unified Multisubstrate Domino Approach for Isatin Synthesis

  摘要：

  Molecular iodine-promoted efficient construction of isatins from 2'-aminophenylacetylenes, 2'-aminostyrenes, and 2'-amino-,beta-ketoesters is developed via oxidative amidation of sp, sp(2), and sp(3) C-H bonds. The reaction involves consecutive iodination, Kornblum oxidation, and intramolecular amidation in a single reactor. The present method meets all of the atom and redox economy principles.

  4-methyl-substituted quinolin-2(1H)-ones smoothly. A synthetic method for highly functionalized quinolin-2(1H)-ones has been developed. The copper(II) chloride-catalyzed aerobic oxidative carbocyclization reactions of α-substituted N-[2-(phenylethynyl)phenyl]acetamides, via the Conia-ene-type intramolecular carbocupration onto the alkynyl moiety, produced 3,4-difunctionalized quinolin-2(1H)-ones. In the absence of

  3-Sulfonyl[1,2,3]triazolo[4,5-b]indoles were efficiently prepared via a tandem catalysis process involving intramolecular ligand stabilized CuAAC and Cu-catalyzed C-N coupling. The obtained 3-sulfonyl[1,2,3]triazolo[4,5-b]indoles could be utilized as a-imino rhodium carbene precursors for the construction of a range of valuable indole molecules including pyrrolo[2,3-b] indoles, spirocyclopropyl iminoindoles, 2,3-dihydropyrrolo[2,3-b]indoles, 3,3'-biindoles, and 2,3'-biindoles.

  An efficient route to enantioenriched propargylamines via a three-component alkynylation reaction using cooperative catalysis with a Cu-I-(i)PrpyboxdiPh complex and N-Boc-(L)-proline has been accomplished. A variety of functionalized amines, aldehydes, and 2-ethynyl anilines were reacted smoothly at ambient temperature to furnish a wide range of propargylamines in high yields (up to 94%) and excellent enantioselectivities (up to 98% ee). Synthetic utility of the methodology has been demonstrated by transforming the products into various synthetically useful intermediates. Finally, propargylamines were transformed into biologically important (indol-2-yl)methanamines over two steps in good yields (up to 88%) with an excellent level of enantioselectivities (up to 95%).
