7-Substituted (Cl, Br, I) indoles were synthesized by using thallation of N-formylindoline as a key reaction. Two precursor tripeptides for the right-hand segment of chloropeptin were synthesized by using (R)-7'-iodo and 7'-bromotryptophans derived from each 7-substituted indole (I, Br) obtained by the above procedure.
以N-甲酰吲哚啉为关键反应,合成了7位取代的(Cl,Br,I)吲哚。通过使用由通过上述方法获得的每个7-取代的吲哚(I,Br)衍生的(R)-7'-碘和7'-溴色氨酸,合成了用于氯肽的右侧部分的两个前体三肽。
