A novel synthetic methodology has been developed for the synthesis of dihydro-β-carboline derivatives employing oxidative amidation–Bischler–Napieralski reaction conditions using tryptamine and 2,2-dibromo-1-phenylethanone as key starting materials. A number of dihydro-β-carboline derivatives have been synthesized in moderate to good yields using this methodology. Attempts were made towards the conversion of these dihydro-β-carbolines to naturally occurring eudistomin alkaloids.
一种新的合成方法已经开发出来,用于合成二氢-β-咔啉衍生物,采用氧化酰胺化-Bischler-Napieralski反应条件,使用色胺和2,2-二溴-1-苯乙酮作为关键起始材料。使用这种方法,合成了多种二氢-β-咔啉衍生物,收率在中等到良好之间。尝试将这些二氢-β-咔啉转化为天然存在的尤地斯托明生物碱。
