Sonogashira coupling reaction with excellent chemoselectivity, affording an inversion of the conventional chemoselectivity order of C–Br > C–Cl > C–OTf. This study also provided an efficient approach to the synthesis of polycyclic aromatic hydrocarbons (PAHs) and the natural product analogue trimethyl-selaginellin L by merging of chemoselective Sonogashira and Suzuki–Miyaura coupling reactions.
一种新开发的在吲哚环上具有C2-环己基的膦配体成功地应用于具有优异化学选择性的化学选择性 Sonogashira 偶联反应中,提供了 C-Br > C-Cl > C-OTf 的常规化学选择性顺序的反转。本研究还为通过化学选择性 Sonogashira 和 Suzuki-Miyaura 偶联反应合成多环芳烃 (PAH) 和天然产物类似物三甲基卷柏素 L 提供了一种有效的方法。
