A novel approach to the synthesis of 3-(alkylsulfanylmethyl)-substituted 1H-indoles was developed based on the Fischer indole synthesis involving accessible β-mercapto ketones. Heterocyclization of 3-[(alkylsulfanyl)methyl]alkan-2-ones and phenylhydrazine by the action of ZnCl2 in MeOH or EtOH gave previously unknown 3-alkyl-3-[(alkylsulfanyl)methyl]-2-methyl-3H-indoles.
基于 Fischer 吲哚合成,涉及可接近的 β-巯基酮,开发了一种合成 3-(烷基硫基甲基)-取代的 1 H-吲哚的新方法。通过 ZnCl 2在 MeOH 或 EtOH 中的作用,3-[(烷基硫烷基)甲基]链烷-2-酮和苯肼的杂环化得到以前未知的 3-烷基-3-[(烷基硫烷基)甲基]-2-甲基-3 H -吲哚。
