  摘要：

  AbstractSyntheses of (partially) aromatic nitrogen heterocycles increasingly rely on transition‐metal catalyzed C−C‐ and C−N‐cross‐coupling reactions. Here we describe a different approach to the synthesis of indolines by a domino C(sp3)−H activation, 1,2‐addition, and defluorinative SNAr‐cyclization sequence to provide the target 1,2‐diarylindolines (1,2‐diaryl‐2,3‐dihydroindoles) from ortho‐fluorinated methyl‐arenes and N‐aryl imines (benzylidene anilines) in a cyclocondensation that is mediated by potassium hexamethyldisilazide (KHMDS) as base exclusively. This transition‐metal‐free process via C−H and C−F bond activation provides a one‐step entry into a wide array of indoline scaffolds (43 examples, up to 96 % yield). This privileged substructure is common in natural products and pharmaceuticals alike, and cannot be accessed by traditional condensation reactions.

  been achieved using imines as reagents and potassium tert-butoxide as the catalyst. Depending on the solvent used, the reaction proceeds by two pathways. In THF, an addition/elimination reaction of exo-cyclic enol ethers with imines provides dihydroisobenzofuran derivatives in good yield. In DMSO, an addition/ring-opening/cyclization cascade reaction occurs with unexpected cleavage of C–O and C–C bonds

• Transition Metal-Free Cascade Reactions of Alkynols to Afford Isoquinolin-1(2<i>H</i>)-one and Dihydroisobenzofuran Derivatives

  Transition metal-free cascade reactions of alkynols with imines have been achieved using potassium tert-butoxide as catalyst. Switching the reaction solvent gives two kinds of products in good yield: isoquinolin-1(2H)-one derivatives and dihydroisobenzofuran derivatives. This approach was used to generate the natural product 8-oxypseudopalmatine in a two-step procedure from commercially available starting materials. Additionally, multicomponent reactions of alkynols, aldehydes, and amines were also successfully achieved to afford isoquinolin-1(2H)-one derivatives.
