molecules has been developed. The strategy involves the condensation of hydrazines with latent aldehydes to ultimately deliver indoline-containing products by way of an interrupted Fischer indolization sequence. The method is convergent, mild, operationally simple, broad in scope, and can be used to access enantioenriched products. In addition, our approach is amenable to the synthesis of furoindoline
已经开发了一种收敛方法来访问存在于大量生物活性分子中的稠合二氢吲哚环系统。该策略涉及肼与潜在醛的缩合,以通过中断的 Fischer 吲哚化序列最终提供含二氢吲哚的产物。该方法收敛、温和、操作简单、适用范围广,可用于获得对映体富集的产品。此外,我们的方法适用于呋喃二氢吲哚和吡咯烷二氢吲哚天然产物的合成,如 physovenine 和 debromoflustramine B 的简洁正式全合成所证明的那样。 该策略可能会合成更复杂的目标,如公社生物碱。
