  从 LPdAr(F) 形成 ArF：芳基三氟甲磺酸酯催化转化为芳基氟化物

  摘要：

  容易氟化 氟原子已成为药物中有用的取代基。然而，合成引入它们仍然具有挑战性，因为目前形成碳氟键的方法需要腐蚀性条件或有些奇特的、因此昂贵的试剂。一个症结是传统钯催化剂未能将芳基与配位氟化物偶联。沃森等人。（第 1661 页，8 月 13 日在线发表；参见 Gouverneur 的 Perspective）表明，将钯与精心设计的膦配体配对可使用简单的氟化物盐产生用于芳基氟化的多功能催化剂。该方法可耐受一系列官能团，并应促进多种含氟芳烃目标的有效合成。催化剂能够使用简单的氟化物盐形成多功能的碳氟键。尽管药物重要性日益增加，但氟化芳族有机分子仍然难以合成。目前的方法需要苛刻的反应条件或高度专业化的试剂，使得复杂氟芳烃的制备具有挑战性。因此，开发克服目前使用的这些技术的局限性的通用制备方法是非常有意义的。我们制备了 [LPd(II)Ar(F)] 配合物，其中 L 是联芳单膦配体，Ar 是芳基，并确定了发生还原消除以形成

  One aspect of the invention relates to a metal-catalyzed conversion of aryl halides and sulfonates to the corresponding aryl fluorides. Another aspect of the invention relates to a metal-catalyzed conversion of heteroaryl halides and sulfonates to the corresponding heteroaryl fluorides. Another aspect of the invention relates to a metal-catalyzed conversion of vinyl halides and sulfonates to the corresponding vinyl fluorides. In certain embodiments, simple fluoride sources, such as AgF and CsF, are used. In certain embodiments, the transformations tolerate a wide range of functional groups, allowing for introduction of fluorine atoms into highly functionalized organic molecules.

  该发明的一个方面涉及将芳基卤化物和磺酸酯金属催化转化为相应的芳基氟化物。该发明的另一个方面涉及将杂环芳基卤化物和磺酸酯金属催化转化为相应的杂环芳基氟化物。该发明的另一个方面涉及将乙烯卤化物和磺酸酯金属催化转化为相应的乙烯氟化物。在某些实施例中，使用简单的氟化物源，如AgF和CsF。在某些实施例中，这些转化可以容忍各种官能团，从而使高度官能化的有机分子中引入氟原子成为可能。

  A flow process for Pd‐catalyzed CF bond formation is described. A microreactor with a packed‐bed design allows for easy handling of large quantities of insoluble CsF with precise control over reaction times, efficient mixing, and the ability to safely handle elevated temperatures and pressures. A variety of aryl triflates, including heteroaryl ones, were converted into aryl fluorides in short reaction

  A new biaryl monophosphine ligand (AlPhos, L1) allows for the room-temperature Pd-catalyzed fluorination of a variety of activated (hetero)aryl trifiates. Furthermore, aryl triflates and bromides that are prone to give mixtures of regioisomeric aryl fluorides with Pd-catalysis can now be converted to the desired aryl fluorides with high regioselectivity. Analysis of the solid-state structures of several Pd(II) complexes, as well as density functional theory (DFT) calculations, shed light on the origin of the enhanced reactivity observed with L1.
• One-Pot, Two-Step, Microwave-Assisted Palladium-Catalyzed Conversion of Aryl Alcohols to Aryl Fluorides via Aryl Nonaflates

  A convenient procedure for converting aryl alcohols to aryl fluorides via aryl nonafluorobutylsulfonates (ArONf) is presented. Moderate to good one-pot, two-step yields were achieved by this nonaflation and microwave-assisted, palladium-catalyzed fluorination sequence. The reductive elimination step was investigated by DFT calculations to compare fluorination with chlorination, proving a larger thermodynamic driving force for the aryl fluoride product. Finally, a key aryl fluoride intermediate for the synthesis of a potent HCV NS3 protease inhibitor was smoothly prepared with the novel protocol.
