Catalysis mediated by iron complexes is emerging as an eco-friendly and inexpensive option in comparison to traditional metal catalysis. The epoxidation of alkenes constitutes an attractive application of iron(III) catalysis, in which terminal olefins are challenging substrates. Herein, we describe our study on the design of biomimetic non-heme ligands for the in situ generation of iron(III) complexes
与传统的金属催化相比,由铁配合物介导的催化正在成为一种环保且廉价的选择。烯烃的环氧化构成了铁(III)催化的有吸引力的应用,其中末端烯烃是具有挑战性的底物。在此,我们描述了我们对用于原位生成铁 (III) 配合物的仿生非血红素配体的设计及其作为末端烯烃环氧化的潜在催化剂的评估。由于众所周知氧化酶的活性位点可能涉及组氨酸的咪唑片段,因此最初评估了各种简单的咪唑衍生物(七种化合物)以寻找最佳反应条件并随后开发更精细的氨基酸衍生肽用于对映选择性环氧化的类似手性配体(10 种衍生物)。
