The synthesis of (aminomethyl), (tosylmethyl), and (aryloxymethyl) indoles starting from indolylmethylacetates with various nucleophiles has been developed. The experimental evidence of the in situ generation of 2-alkylideneindolenines and 3-alkylideneindoleninium as reaction intermediates has been provided through ESI-MS and IRMPD spectroscopy analysis.
从吲哚甲基乙酸酯和各种亲核试剂开始,合成了(氨基甲基)、(甲苯磺酰甲基)和(芳氧基甲基)吲哚。通过 ESI-MS 和 IRMPD 光谱分析提供了原位生成 2-亚烷基吲哚和 3-亚烷基吲哚作为反应中间体的实验证据。
