Sodium Iodide/Hydrogen Peroxide-Mediated Oxidation/Lactonization for the Construction of Spirocyclic Oxindole-Lactones
Li, Guofeng,Huang, Liwu,Xu, Jiecheng,Sun, Wangsheng,Xie, Junqiu,Hong, Liang,Wang, Rui
supporting information, p. 2873 - 2877 (2016/09/16)
The sodium iodide/hydrogen peroxide-mediated oxidation/lactonization of indolepropionic acids was achieved, affording the corresponding spirocyclic oxindole-lactones in moderate to high yields. This metal-free procedure features mild reaction conditions, non-toxicity and easy handling, with hydrogen peroxide (H2O2) as a clean oxidant. (Figure presented.).

supporting information, p. 7073 - 7076 (2015/08/19)
CuCl2/TBHP-mediated direct chlorooxidation of indole derivatives under simple aerobic conditions was reported, leading to facile preparations of a range of 3,3-disubstituted 3-chlorooxindoles in good yields and selectivities.
Thee-component, one-pot synthesis of hexahydroazepino[3,4-b]indole and tetrahydro-1H-pyrido[3,4-b]indole derivatives and evaluation of their cytotoxicity
Reddy, B.V. Subba,Venkata Ganesh,Vani,Ramalinga Murthy,Kalivendi, Shasi V,Yadav
supporting information, p. 4501 - 4503 (2015/02/06)
A three-component, four-center Ugi reaction has been developed to produce a novel class of 2-aryl-3-oxo-hexahydroazepino[3,4-b]indole and 2-aryl-3-oxo-tetrahydro-1H-pyrido[3,4-b]indole derivatives in good to high yields. A few of them exhibit moderate cyt

Efficient synthesis of tetrahydro-b-carbolin-1-one and dihydroisoquinolin- 1-one derivatives as versatile Intermediates
Judd, Katie E.,Mahon, Mary F.,Caggiano, Lorenzo
experimental part, p. 2809 - 2817 (2010/01/21)
An efficient one-pot procedure is described in which an isocyanate intermediate, generated from the corresponding carboxylic acid by a modified Curtius rearrangement, is captured by a tethered aromatic ring in the presence of BF3?OEt2 to generate various
New small molecule inhibitors of hepatitis C virus
Wei, Wanguo,Cai, Cuifang,Kota, Smitha,Takahashi, Virginia,Ni, Feng,Strosberg, A. Donny,Snyder, John K.
scheme or table, p. 6926 - 6930 (2010/06/16)
New small molecule inhibitors of HCV were discovered by screening a small library of indoline alkaloid-type compounds. An automated assay format was employed which allowed identification of dimerization inhibitors of core, the capsid protein of the virus. These compounds were subsequently shown to block production of infectious virus in hepatoma cells.
Addition of heterocycles to electron deficient olefins and alkynes catalyzed by gold(III)
Li, Zigang,Shi, Zhangjie,He, Chuan
, p. 5049 - 5054 (2007/10/03)
A gold(III)-catalyzed hydroarylation of different olefins is reported here. AuCl3 works as an excellent catalyst to mediate reactions between various heterocycles and electron deficient olefins and alkynes under mild conditions. This gold(III)-based method tolerates different functional groups such as aldehyde, carboxylic acid, nitrile, and is highly efficient. We have shown that some of these reactions complete in minutes at room temperature.
Intramolecular Ritter reactions of 2-(2-cyanoethyl)tetrahydrocyclopenta-[b] indole and -carbazole derivatives

Intramolecular Ritter reactions of 2-(2-cyanoethyl)tetrahydrocyclopenta[b] indole and -carbazole derivatives, prepared by a sequence of two different α-substitutions and Grignard reactions of the indole-based ketones 4-methyl-1,4-dihydrocyclopenta[b]indol-3(2H)-one and 9-methyl-2,3,4,9- tetrahydro-1H-carbazol-1-one, were used as key steps in the construction of various tetracyclic lactam compounds.
