The first examples of amide-tethered aminohydroxylation reactions, catalyzed by osmium, showing that the use of N−O-based reoxidants are essential for success, are reported. The system that is described is compatible with a variety of different alkene substitution patterns and ring sizes and works with low loadings in both cyclic and acyclic systems. The levels of diastereoselectivity that were observed
据报道,催化的酰胺束缚的氨基羟基化反应的第一个例子表明,使用基于N-O的再氧化剂对成功至关重要。所描述的系统与多种不同的烯烃取代方式和环大小兼容,并且在环状和非环状系统中均以低负荷运行。对于在有机合成中使用立体选择性TA反应而言,对于在烯丙基和烯丙基位置上的取代基都观察到的非对映选择性水平很好。
