The synthesis of 1-methyl-3-(dimethylaminomethyl)indol-2-yl, 3-(dimethylaminomethyl)indol-2-yl, 2-(dimethylaminomethyl)indol-3-yl, and 2-methoxymethylindol-3-yl 1,2,5,6-tetrahydro-1-methylpyridin-4-yl ketones is described. Although each of these could be isomerised to the corresponding cyclic enamine (2-piperideine), only in the first case could the result of intramolecular β-alkylation of the enamine
1-甲基-3-(二甲基氨基甲基)吲哚-2-基,3-(二甲基氨基甲基)吲哚-2-基,2-(二甲基氨基甲基)吲哚-3-基和2-甲氧基甲基吲哚-3-基的合成1,描述了2,5,6-四氢-1-甲基吡啶-4-基酮。尽管每个都可以异构化为相应的环状烯胺(2-哌啶),但只有在第一种情况下,才能获得烯胺分子内β-烷基化的结果,即。2,3,4,6-四氢-5-羟基-2,6-二甲基-1 H-吡啶基[4.3- b ]咔唑(9a)。
