N-trimethylsilyloxymethylpyroglutamate is the best method to obtain methyl N-indolylmethylpyroglutamate. Friedel-Crafts cyclization of the corresponding acid yields a new ketone (1,2,3,5,11,11a-hexahydroindolizino[7,6-b] indole-3,11-dione).
N-三甲基甲硅烷基吲哚与N-三甲基甲硅烷基氧基甲基焦谷氨酸的缩合反应是获得N-吲哚基甲基焦谷氨酸甲酯的最佳方法。相应酸的Friedel-Crafts环化反应产生新的酮(1,2,3,5,11,11a-六氢吲哚并[7,6 - b ]吲哚-3,11-二酮)。
