scale from 2-methyl-5-nitroisoquinolinium iodide. Subsequent alkaline hydrolysis afforded 4-methyiaminomethylindole. Starting from these two compounds, various 3,4-di- and 4-substituted indoles were prepared including 4-formylindole, 4-[N,N-disubstituted]aminomethylindoles, 4-alkylindoles, and benz[cd]indoles. A novel nucleophilic substitution reaction of gramine derivatives by the catalysis of tri-n-butylphosphine
4-[N-乙酰基-N-甲基]氨基甲基吲哚是从2-甲基-5-硝基异喹啉碘化物大规模经济地制备的。随后的碱水解得到4-甲基氨基甲基吲哚。从这两种化合物开始,制备了各种 3,4-二-和 4-取代的吲哚,包括 4-甲酰基吲哚、4-[N,N-二取代]氨基甲基吲哚、4-烷基吲哚和苯并[cd] 吲哚。还报道了通过三正丁基膦催化的禾本科胺衍生物的新型亲核取代反应。
