Biologically interesting fused oligocyclic lactams have been prepared via an intramolecular redox-neutral cyclization process. By the proper choice of the substrates with a wide variety of tethered olefins, the less favored CâH bond can be activated and functionalized. This CâH activation proceeds under mild conditions, obviates the need for external oxidants, and displays a broad scope with respect to the substituents.
生物学上引人关注的融合多环内酰胺已通过一种分子内氧化还原中性环化过程制备。通过适当选择带有多种侧链烯烃的底物,可以激活并功能化较不利的C-H键。这种C-H键的活化在温和条件下进行,无需外部氧化剂,并且对取代基具有广泛的适用性。
