An efficient method for the synthesis of tryptophan analogues has been developed via one-pot reaction of commercial available indoles, ethyl nitroacetate, and paraformaldehyde in the presence of molecular sieves. The reaction provided tryptophan nitro-precursors in moderate to good yields, which were further converted to α-hydroxymethylated tryptophan derivatives catalyzed by DABCO in high yields.
通过在分子筛的存在下市售吲哚,硝基乙酸乙酯和多聚甲醛的一锅反应,已经开发了一种合成色氨酸类似物的有效方法。该反应以中等至良好的产率提供了色氨酸硝基前体,然后将其进一步转化为由DABCO催化的高产率的α-羟甲基化的色氨酸衍生物。
