The complex base NaNH2-tBuONa allows expeditious synthesis of indole derivatives by arynic cyclization of imines or enamines of chloroanilines. Unstable may be used without purification, complex bases being unsensitive to impurities.
复杂的碱式NaNH 2 -tBuONa可以通过亚胺或氯苯胺的烯胺的芳基环化反应迅速合成吲哚衍生物。不稳定,无需纯化即可使用,复杂的碱对杂质不敏感。
