an investigation of a peptide-based catalyst (6) that is effective for the site- (>100:1:1) and enantioselective epoxidation (86% ee) of farnesol. Studies of the substrate scope exhibited by the catalyst are included, along with an exploration of optimized reaction conditions. Mechanistic studies are reported, including relative rate determinations for the catalyst and propionic acid, a historical perspective
我们详细介绍了对基于肽的催化剂 ( 6 ) 的研究,该催化剂对位点有效 - (>100 : 1 : 1) 和金合欢醇的对映选择性环氧化 (86% ee)。包括对催化剂所表现出的底物范围的研究,以及对优化反应条件的探索。报道了机理研究,包括催化剂和丙酸的相对速率测定、历史视角、截断研究和使用 NMR 数据建模。我们汇编的数据增进了我们对通过组合手段识别的催化剂内部工作原理的理解。
