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。

selective oxidation of the 2-methyl group and the formation of 3-alkyl-2-formylindoles. The formation of the 2-formylindoles was dependent on the nature of the solvent used. The treatment of 3-benzoyl-1,2-dimethylindole with silver acetate gave 2-acetoxymethyl-3-benzoyl-1-methylindole and 3-benzoyl-2-formyl-1-methylindole. The mechanistic implications for the autoxidation and the oxidation with silver
