An organocatalytic enantioselective formal hydroarylation of 2-vinyl indoles for the preparation of enantioenriched 2,3′-bis(indolyl)methanes bearing an all-carbonquaternarystereocenter is described. This reaction features mild conditions, low catalyst loading, excellent efficiency and enantioselectivity. The obtained products showed promising anticancer activity.
Selective Synthesis of Quinolines and Indoles: Sulfur-Assisted or Selenium-Catalyzed Reaction of β-(2-Nitrophenyl)-α,β-unsaturated Ketones with Carbon Monoxide
A simple and selective synthetic method of quinolines and indoles by the reaction of β-(2-nitrophenyl)-α,β-unsaturatedketones with carbonmonoxide was developed. When β-(2-nitrophenyl)-α,β-unsaturatedketones were allowed to react with carbonmonoxide and water in the presence of a stoichiometric amount of sulfur or a catalytic amount of selenium, the corresponding quinolines were produced in moderate-to-good

Pd‐catalysed annulationreactions between indole derivatives and internal alkyne esters leading to various pyrrolo[1,2‐a]indoles and pyrroloquinolines have been developed. The strategy involves an intermolecular addition of the indole nitrogen on to the internal alkyne ester followed by an intramolecular insertion of a vinyl–palladium complex into the carbonyl group. This method offers a facile and
吲哚衍生物与内部炔烃酯之间的钯催化环化反应已开发出各种吡咯并[1,2- a ]吲哚和吡咯并喹啉。该策略涉及将吲哚氮分子间添加到内部炔烃酯上,然后将乙烯基钯复合物分子内插入羰基中。该方法为吡咯并[1,2- a ]吲哚和吡咯并喹啉提供了一种简便实用的方法。
