developed for the synthesis of 2-acylquinolines from methyl ketones and arylamines using 1,4-dithane-2,5-diol as an ethylene surrogate. Moreover, the investigation of the mechanism suggested that this reaction occurred via an iodination/Kornblum oxidation/Povarov/aromatization sequence. It is noteworthy that the arylamine substrate also played an important role in promoting the reaction.
已开发出一种高效的I 2促进的正式[4 + 2]环加成反应,用于使用1,4-二烷-2,5-二醇作为乙烯代用品,由甲基酮和芳基胺合成2-酰基喹啉。此外,对该机理的研究表明该反应是通过碘化/ Kornblum氧化/ Povarov /芳构化顺序发生的。值得注意的是,芳基胺底物在促进反应中也起重要作用。
