Functionalized spiro-tetrahydro-β-carbolines were formed by an efficient gold(I)-catalyzed rearrangement reaction of alkynylaziridine indoles. The reaction involved a Friedel-Crafts type intramolecular reaction of alkynylaziridine indoles, following by hydroamination of aminoallene intermediate.

Based on the chemical structure of Pyrroloquinoline quinone (PQQ), a novel class of indole-2-carboxylate derivatives was designed, synthesized and assayed for antiproliferative activity in cancer cells in vitro. The biological results showed that some der
Synthesis of chromeno[3,4-b]indoles as Lamellarin D analogues: A novel DYRK1A inhibitor class
Neagoie, Cleopatra,Vedrenne, Emeline,Buron, Frédéric,Mérour, Jean-Yves,Rosca, Sorin,Bourg, Stéphane,Lozach, Olivier,Meijer, Laurent,Baldeyrou, Brigitte,Lansiaux, Amelie,Routier, Sylvain
experimental part, p. 379 - 396 (2012/04/10)
A library of substituted chromeno[3,4-b]indoles was developed as Lamellarin isosters. Synthesis was achieved from indoles after a four-step pathway sequence involving C-3 iodination, a Suzuki cross-coupling reaction, and a one pot deprotection/lactonisation step. Twenty final compounds were tested in order to determine their activity against topoisomerase I and kinases, the two major biological activities of Lamellarins. One newly synthesized derivative exhibited a strong topoisomerase activity comparable to reference compounds such as campthotecin and Lamellarin with only a weak kinase inhibition. Two other lead compounds were identified as new nanomolar DYRK1A inhibitors and several other drugs affected the kinases in the sub-micromolar range. These results will enable us to use the chromeno[3,4-b]indole as a pharmacophore to develop potent treatments for neurological or oncological disorders in which DYRK1A is fully involved.

supporting information; experimental part, p. 2012 - 2014 (2011/06/28)
A practical iron-catalyzed intramolecular C-H amination reaction and its application in the synthesis of indole derivatives are presented. As a catalyst, commercially available iron(II) triflate is used.
Intramolecular C-H amination reactions: Exploitation of the Rh 2(II)-catalyzed decomposition of azidoacrylates
Stokes, Benjamin J.,Dong, Huijun,Leslie, Brooke E.,Pumphrey, Ashley L.,Driver, Tom G.
, p. 7500 - 7501 (2008/02/09)
Rhodium(II) perfluorobutyrate-mediated decomposition of vinyl azides provides a new, mild entry into Rh2(II) nitrenoid chemistry. This methodology allows rapid access to a variety of complex, functionalized N-heterocycles in two steps from commercially available starting materials. Copyright
Solvent-free Heck-Jeffery reactions under ball-milling conditions applied to the synthesis of unnatural amino acids precursors and indoles
Tullberg, Erik,Schacher, Felix,Peters, Dan,Frejd, Torbjoern
, p. 1183 - 1189 (2007/10/03)
The syntheses of various amino- and hydroxy-substituted dehydrophenylalanine derivatives using the Heck-Jeffery protocol under non-solvent conditions in a ball mill are presented. The influences of electron-withdrawing groups and of the location of the heteroatom substituent relative to the halide are discussed. Suitably substituted ortho-amino dehydrophenylalanine derivatives undergo a cyclization-elimination reaction to the corresponding 2-substituted indoles. Georg Thieme Verlag Stuttgart.
