total synthesis of cytotoxic indole alkaloids phidianidine A and B is described. Rapid assembly of the 1,2,4-oxadiazole core from a novel N-hydroxyguanidine and the corresponding indole-3-acetic acid chloride led to formal syntheses of phidianidine A and B in only three steps from known compounds. Deprotection under standard conditions provided the trifluoroacetate salts of phidianidine A and B in quantitative
描述了最短的细胞毒性吲哚生物碱phidianidine A和B的总合成。由新颖的N-羟基胍和相应的吲哚-3-乙酸氯迅速组装成1,2,4-恶二唑核,仅需三步即可从已知化合物中正式合成phidianidine A和B。在标准条件下进行脱保护,以定量收率得到phidianidine A和B的三氟乙酸盐。
