Phidianidine B (1), a natural 1,2,4-oxadiazole linking both an indole system and an aminoalkyl guanidine group that has been recently reported from a marine mollusk, has been synthesized in seven steps (14% total yield). The synthetic procedure, which is based on the coupling of 3indolacetic acid methyl ester and the amino-alkyl hydroxy guanidine intermediate 2, opportunely prepared, is of general
Phidianidine B (1) 是一种天然 1,2,4-恶二唑,可连接吲哚系统和最近从海洋软体动物中报道的氨基烷基胍基团,分七步合成(总产率 14%)。该合成程序基于 3 吲哚乙酸甲酯和氨基-烷基羟基胍中间体 2 的偶合,适时制备,具有普遍应用性,可以合成具有不同烷基链长度或吲哚环取代的类似物.
