  The limited availability of catalytic reaction components may represent a major hurdle for the practical application of many catalytic procedures in organic synthesis. In this work, we demonstrate that the mixture of isomeric iron complexes [Fe(OTf)2(mix-BPBP)] (mix-1), composed of Λ-α-[Fe(OTf)2(S,S-BPBP)] (S,S-1), Δ-α-[Fe(OTf)2(R,R-BPBP)] (R,R-1) and Δ/Λ-β-[Fe(OTf)2(R,S-BPBP)] (R,S-1), is a practical catalyst for the preparative oxidation of various aliphatic compounds including model hydrocarbons and optically pure natural products using hydrogen peroxide as an oxidant. Among the species present in mix-1, S,S-1 and R,R-1 are catalytically active, act independently and represent ca. 75% of mix-1. The remaining 25% of mix-1 is represented by mesomeric R,S-1 which nominally plays a spectator role in both C–H and CC bond oxidation reactions. Overall, this mixture of iron complexes displays the same catalytic profile as its enantiopure components that have been previously used separately in sp3 C–H oxidations. In contrast to them, mix-1 is readily available on a multi-gram scale via two high yielding steps from crude DL/meso-2,2′-bipyrrolidine. Next to its use in C–H oxidation, mix-1 is active in chemospecific epoxidation reactions, which has allowed us to develop a practical catalytic protocol for the synthesis of epoxides.

  催化反应组分的有限可用性可能成为许多催化过程在有机合成中实际应用的主要障碍。本工作中,我们证明了由异构铁配合物[Fe(OTf)2(mix-BPBP)] (mix-1)组成的混合物,包括λ-α-[Fe(OTf)2(S,S-BPBP)] (S,S-1)、Δ-α-[Fe(OTf)2(R,R-BPBP)] (R,R-1)和Δ/λ-β-[Fe(OTf)2(R,S-BPBP)] (R,S-1),是使用过氧化氢作为氧化剂对包括模型烃和光学纯天然产物在内的各种脂肪族化合物进行制备氧化的实用催化剂。在mix-1中存在的物种中,S,S-1和R,R-1是催化活性的,独立作用,约占mix-1的75%。剩余的25%由介观R,S-1代表,名义上在C–H和CC键氧化反应中起旁观者作用。总体而言,这种铁配合物混合物显示出与其先前分别用于sp3 C–H氧化的纯对映体组分相同的催化特征。与它们不同的是,mix-1可通过从粗DL/中二吡咯烷的两个高产率步骤大量制备。除了用于C–H氧化外,mix-1在化学选择性环氧化反应中也表现出活性,这使我们能够开发出一种用于环氧化合物合成的实用催化方案。

  The invention provides novel manganese catalysts such as [Mn( t BuPc)], which are general for the amination of all types of C(sp 3 )-H bonds (aliphatic, allylic, propargylic, benzylic, ethereal), including strong 1 o aliphatic C—H bonds, while achieving excellent chemoselectivity, stereospecificity, and high functional group tolerance. We demonstrate the late-stage diversification of bioactive complex molecules that encompass the range of C(sp 3 )-H bond types, such as selective 1 o C—H aminations of betulinic acid and pleuromutilin derivatives. The catalysts' unprecedented balance of reactivity and selectivity is in part attributed to its mechanism of C—H amination that lies between stepwise and concerted.

  该发明提供了新型的锰催化剂，如[Mn(tBuPc)]，适用于所有类型的C(sp3)-H键（脂肪族、烯丙基、丙炔基、苄基、乙醚基）的胺化，包括强1°脂肪族C—H键，同时实现优异的化学选择性、立体特异性和高官能团耐受性。我们展示了包括选择性1°C—H键胺化在内的生物活性复合分子的晚期多样化，这些复合分子涵盖了各种C(sp3)-H键类型，如对苯二酚酸和普鲁莫铁霉素衍生物的选择性1°C—H键胺化。催化剂在反应性和选择性之间的前所未有的平衡部分归因于其C—H键胺化机制介于逐步和协同之间。

  A composition including a complex of a metal, a tetradentate ligand, at least one ancillary ligand, and a counterion may be used for selective sp 3 C—H bond oxidation. The tetradentate ligand may include a N-heterocyclic-N,N′-bis(pyridyl)-ethane-1,2-diamine group or a N,N′-bis(heterocyclic)-N,N′-bis(pyridyl)-ethane-1,2-diamine group. The composition can be used in combination with H 2 O 2 to effect highly selective oxidations of unactivated sp 3 C—H bonds over a broad range of substrates. The site of oxidation can be predicted, based on the electronic and/or steric environment of the C—H bond. In addition, the oxidation reaction does not require the presence of directing groups in the substrate.
