contrary: Utilizing the [Pd(quinox)]–TBHP catalyst system, protectedallylicamines were oxidized with high selectivity for the methyl ketone product. This is contrary to the results obtained by the substrate‐controlled Tsuji–Wacker oxidation, which highlights the catalyst‐controlled system presented here (see scheme). A variety of N‐protecting groups undergo selective oxidation with high ketone selectivity
相反:利用 [Pd(quinox)]-TBHP 催化剂体系,受保护的烯丙胺被氧化,具有高选择性,生成甲基酮产物。这与通过底物控制的 Tsuji-Wacker 氧化获得的结果相反,这突出了此处介绍的催化剂控制系统(参见方案)。各种 N 保护基团以高酮选择性进行选择性氧化。TBHP=叔丁基过氧化氢。
