temperature that exhibit a broad functional-group tolerance. More water leads to monoarylation, while less water leads to diarylation. Further one-step transformation afforded oxidized bis(indolyl)methanes, eudistomin U, and the related derivatives in satisfactory yields.
水在有机合成中起着至关重要的作用。然而,由水操纵的多种功能化仍然很少,并且仍未开发。在这里,我们报道了第一个水操纵的协议,以实现在室温下开放的烧瓶中四氢-β-咔啉(THβCs)的多样化功能化,表现出宽泛的官能团耐受性。更多的水导致单芳基化,而更少的水导致二芳基化。进一步的一步转化以令人满意的产率提供了氧化的双(吲哚基)甲烷,芥子油苷U和相关的衍生物。
