  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

  日期：1993.12

  Treatment of N-(2-bromoaryl) enaminones 4, prepared by several different methods, with palladium (II) acetate, triarylphosphine and triethylamine in boiling acetonitrile gave pyrrolo[1,2-a]indoles 8 yields of 50% – 100%. The hydroxy-substituted products 8k could be oxidised to the mitosene-like quinone 9 with Fremy's salt.

• Oxidative Radical Cyclization of (.omega.-Iodoalkyl)indoles and Pyrroles. Synthesis of (-)-Monomorine and Three Diastereomers

  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).
• Development of Madelung-Type Indole Synthesis Using Copper-Catalyzed Amidation/Condensation Strategy
  作者：Yoshinori Kondo、Masahiro Abe、Charline Denneval、Kanako Nozawa-Kumada

  DOI：10.3987/com-16-13440

  日期：——

  A new method for Madelung-type indole synthesis was investigated, and it was found that the amidation of 2-iodophenylacetonitrile with various alkanamides proceeds smoothly in the presence of CuI and a diamine ligand. The subsequent cyclization of the C-N coupling products takes place under the coupling reaction conditions.
