  Enantioselective Radiosynthesis of Positron Emission Tomography (PET) Tracers Containing [¹⁸F]Fluorohydrins

  摘要：

  Herein, we describe an operationally straightforward radiosynthesis of a chiral transition metal fluoride catalyst, [F-18](salen)CoF, and its use for late-stage enantioselective aliphatic radiofluorination. We demonstrate the utility of the method by preparing single enantiomer experimental and clinically validated PET tracers that contain base-sensitive functional groups, epimerizable stereocenters, and nitrogen-rich motifs. Unlike the conventional radiosyntheses of these targets with [F-18]KF, labeling with (salen)CoF is possible in the last step and under exceptionally mild conditions. These results constitute a rare example of a nucleophilic radiofluorination using a transition metal fluoride and highlight the potential of such reagents to enhance traditional methods for labeling aliphatic hydrocarbons.

  Herein we report the reductive coupling of electronically unbiased olefins with imines and aldehydes. Iron catalysis allows addition of alkyl-substituted olefins into imines through the intermediacy of free radicals, whereas a combination of catalytic Co(Sal t-Bu, t-Bu) and chromium salts enables a branch-selective coupling of olefins and aldehydes through the formation of a putative alkyl chromium intermediate

  terminal epoxides with catalyst 3b4 (Scheme 1, Nu ) OH) suggested that (salen)Co(III) complexes might also serve as effective catalysts for the enantioselective addition of phenols to epoxides. This strategy has proven successful, and we report here the first examples of kinetic resolution of epoxides with phenols, with the isolation of 1-aryloxy 2-alcohols (1) in high ee’s and yields.

  钴/镍双催化末端烯烃与碘芳烃的加氢芳基化利用容易获得的起始材料构建了复杂性，并且高度优先选择马尔可夫尼科夫（支化）产物。在这里，我们通过使用反应进程动力学分析（RPKA）、自由基时钟实验和化学计量研究，提出了该反应的机理模型。通过排除竞争假设，我们得出结论，该反应通过前所未有的烷基钴到镍的直接金属转移进行。通过有机钴物质的光谱观察，催化烯烃预官能化的演示将这种 Csp2-Csp3 交叉偶联方法与传统的金属转移过程（采用化学计量的有机金属亲核试剂）和有机卤化物跨镍的双金属氧化加成区别开来，描述为自由基断裂和随后的烷基自由基在第二个镍中心捕获。对反应的深入理解导致了优化的加氢芳基化程序，排除了外源氧化剂，证明金属转移是净氧化还原中性的。钴催化烯烃预官能化以及通过直接金属转移与镍催化循环的接触提供了一个新平台，以预备有用的方式融合这两个丰富的化学领域。
