  • Highly Stereoselective Assembly of Polycyclic Molecules from 1,6-Enynes Triggered by Rhodium(III)-Catalyzed C–H Activation
    作者:Heng Lu、Zhoulong Fan、Chaodong Xiong、Ao Zhang

    日期:2018.5.18
    An Rh(III)-catalyzed C–H activation of pyrazolones with 1,6-enynes was investigated. The regioselectivity of the C–H activation/alkyne insertion is readily solved by using symmetric enyne coupling partners, and a C–H activation-triggered cascade reaction is realized, which involves alkyne insertion, tautomerization, and double cyclization to offer a class of structurally complex polycyclic architectures
    研究了Rh(III)催化吡唑啉酮与1,6-烯炔的C–H活化。通过使用对称的烯炔偶合剂可轻松解决C–H激活/炔烃插入的区域选择性,并实现了C–H激活触发的级联反应,其中涉及炔烃插入,互变异构和双环化,从而提供了一类结构复杂的多环架构。这种级联反应可在高区域选择性和立体专一性上耐受广泛的底物范围,并在一次操作中提供三个新的化学键和四个手性中心。进行了多环支架的各种衍生化,为产物提供了足够的空间用于进一步的功能转化。
