Herein, we have designed and demonstrated a copper-catalyzed intramolecular SEAr reaction−oxidation process to access styryl-/alkenyl-substituted xanthone derivatives. This protocol affords a variety of substituted xanthone derivatives in moderate to high yields. The protocol has been demonstrated by gram-scale syntheses.
在此,我们设计并展示了一种铜催化的分子内 S E Ar 反应-氧化过程,以获得苯乙烯基/烯基取代的氧杂蒽酮衍生物。该协议提供了多种中等至高产率的取代氧杂蒽酮衍生物。该协议已通过克级合成得到证明。
