  taking a first-principles approach guided by computation, these new mediators were identified and rapidly expanded into a library using ubiquitous building blocks and trivial synthesis techniques. The ylide-based approach to C–H oxidation exhibits tunable selectivity that is often exclusive to this class of oxidants and can be applied to real-world problems in the agricultural and pharmaceutical sectors

  强 C(sp 3 )-H 键的位点特异性氧化在有机合成中具有无可争议的效用。从简化对代谢物的获取和先导化合物的后期多样化到截断逆合成计划，学术界和工业界都越来越需要新的试剂和方法来实现这种转变。当前化学试剂的一个主要缺点是在结构和反应性方面缺乏多样性，这阻碍了用于快速筛选的组合方法的使用。在这方面，定向进化仍然最有希望在各种复杂环境中实现复杂的 C-H 氧化。在此，我们提出了一个设计合理的平台，该平台使用N-铵叶立德作为电化学驱动的氧化剂，用于位点特异性、化学选择性 C(sp 3 )-H 氧化。通过采用以计算为指导的第一性原理方法，这些新的介质被识别出来，并使用无处不在的构建块和简单的合成技术迅速扩展到一个库中。基于叶立德的 C-H 氧化方法表现出可调的选择性，这通常是此类氧化剂独有的，可应用于农业和制药领域的实际问题。

  The efficient and selective oxidation of secondary CH sites of alkanes is achieved by using low catalyst loadings of a non‐expensive, readily available iron catalyst [Fe(II)(CF3SO3)2(mcp)], Fe‐mcp, [mcp=N,N′‐dimethyl‐N,N′‐bis(2‐pyridylmethyl)cyclohexane‐trans‐1,2‐diamine]}, and hydrogen peroxide (H2O2) as oxidant, via a simple reaction protocol. Natural products are selectively oxidized and isolated

• Regioselective Oxidation of Nonactivated Alkyl C–H Groups Using Highly Structured Non-Heme Iron Catalysts

  Selective oxidation of alkyl C-H groups constitutes one of the highest challenges in organic synthesis. In this work, we show that mononuclear iron coordination complexes Lambda-[Fe(CF3SO3)(2)((S,S,R)-MCPP)] (Lambda-1P), Delta-[Fe(CF3SO3)(2)((R,R,R)-MCPP)] (Delta-1P), Lambda-[Fe(CF3SO3)(2)((S,S,R)-BPBPP)] (Lambda-2P), and Delta-[Fe(CF3SO3)(2)((R,R,R)-BPBPP)] (Delta-2P) catalyze the fast, efficient, and selective oxidation of nonactivated alkyl C-H groups employing H2O2 as terminal oxidant. These complexes are based on tetradentate N-based ligands and contain iron centers embedded in highly structured coordination sites defined by two bulky 4,5-pinenopyridine donor ligands, a chiral diamine ligand backbone, and chirality at the metal (Lambda or Delta). X-ray diffraction analysis shows that in Lambda-1P and Lambda-2P the pinene rings create cavity-like structures that isolate the iron site. The efficiency and regioselectivity in catalytic C-H oxidation reactions of these structurally rich complexes has been compared with those of Lambda-[Fe(CF3SO3)(2)((S,S)-MCP)] (Lambda-1), Lambda-[Fe(CF3SO3)(2)((S,S)-BPBP)] (Lambda-2), Delta-[Fe(CF3SO3)(2)((R,R)-BPBP)] (Delta-2), Lambda-[Fe(CH3CN)(2)((S,S)-BPBP)] (SbF6)(2) (Lambda-2SbF(6)), and Delta-[Fe(CH3CN)(2)((R,R)-BPBP)](SbF6)(2) (Delta-2SbF(6)), which lack the steric bulk introduced by the pinene rings. Cavity-containing complexes Lambda-1P and Lambda-2P exhibit enhanced activity in comparison with Delta-1P, Delta-2P, Lambda-1, Lambda-2, and Lambda-2SbF(6). The regioselectivity exhibited by catalysts Lambda-1P, Lambda-2P, Delta-1P, and Delta-2P in the C-H oxidation of simple organic molecules can be predicted on the basis of the innate properties of the distinct C-H groups of the substrate. However, in specific complex organic molecules where oxidation of multiple C-H sites is competitive, the highly elaborate structure of the catalysts allows modulation of C-H regioselectivity between the oxidation of tertiary and secondary C-H groups and also among multiple methylene sites, providing oxidation products in synthetically valuable yields. These selectivities complement those accomplished with structurally simpler oxidants, including non-heme iron catalysts Lambda-2 and Lambda-2SbF(6).
