  Pd(II)-catalyzed intramolecular aminopalladation/direct C–H arylation under aerobic conditions: synthesis of pyrrolo[1,2-a]indoles

  摘要：

  Heating a DMA/pivalic acid (v/v=4/1) solution of diversely substituted 6-(phenylamino)hex-2-ynoates in the presence of a catalytic amount of Pd(OAc)(2) under oxygen atmosphere afforded pyrrolo[1,2-a]indoles in moderate to good yields. A domino sequence involving intramolecular aminopalladation followed by C-H activation and reductive elimination was proposed to account for the observed bis-cyclization. (C) 2013 Elsevier Ltd.

• Expeditious synthesis of multisubstituted indoles <i>via</i> multiple hydrogen transfers
  作者：Taira Yoshida、Keiji Mori

  DOI：10.1039/c8cc07009a

  日期：——

  types of hydrogen transfer processes ([1,5]-hydride shift, proton transfer, and [1,2]-hydride shift) occurred to give various 3-alkoxycarbonylindoles. Further study revealed that a [1,2]-alkyl shift instead of a [1,2]-hydride shift proceeded to afford 3-alkylindoles from the substrates with an amino group having tertiary carbons adjacent to a nitrogen atom.

  lactam moiety dihydropyrrolo- (10), tetrahydropyrido[1,2-]indole (11), or dihydro-1-1-benzazeptne (12) derivatives are foraed. Pyrrolo[1,2-]indole 10c has been converted into the corresponding quinone 15b. Starting from naphthaleneacetonitrile 20, prepared in 5 steps fron 2,3-dichloronaphthoquinone, the 5,10-dioxo-1-pyrrolo[1,2-] benz []indole 22 is obtained upon treatment with base and subsequent oxidation

  protocol for the preparation of cycloalkano[1,2-a]indoles by way of an intramolecular alkyl migration reaction in cyclic indolylborates is described. NaOMe was found to act as a successful trialkylboryl-protecting group against to the lithiation at the C2 of the indole ring. Treatment of cyclic indolylborates with electrophiles produced cycloalkano-[1,2-a]indoles.

• Oxidative Radical Cyclization of (.omega.-Iodoalkyl)indoles and Pyrroles. Synthesis of (-)-Monomorine and Three Diastereomers
  作者：Dean R. Artis、In-Seop Cho、Saul Jaime-Figueroa、Joseph M. Muchowski

  日期：1994.5

  Addition of excess hydrogen peroxide (10 equiv) to a sonicated solution of FeSO4:7H(2)O (1 equiv) in Dh ISO containing the N-(omega-iodoalkyl)indoles 4, 5, 11, and 13 effected oxidative radical cyclization to 6, 7, 14, and 15, respectively. The (omega-iodoalkyl)pyrroles 21, 22, 27, 38, and 49 underwent analogous cyclization reactions to 23, 24, 28, 39, and 50, respectively. The regiochemistry of these radical cyclization reactions was correctly predicted by FMO calculations in all cases but one. For compound 38, FMO calculations indicated that radical attack should take place at both C-3 and C-5. Only the product of cyclization at C-5, i.e., 39, was observed. The enantiomerically pure bicyclic ketone 42, prepared by the above technique from the iodide 53, was converted into 55 which, on catalytic reduction (H-2/Rh-A1(2)O(3)), gave a mixture of (-)-monomorine (40) and three of its diastereomers 56-58 (see, however, Note Added in Proof).
