  Direct synthesis of ortho-dihalogenated arylpyrimidines using calcium halides as halogen sources

  摘要：

  Pyrimidines and their derivatives have been used as important motifs in materials and medicinal chemistry. In this Letter, a wide variety of ortho-dihalogenated arylpyrimidines were synthesized with high yields and functional-group tolerance using calcium halides as crucial halogenating agents and cupric trifluoroacetate as oxidant in the presence of air. The generated dichlorinated products could be further manipulated by stepwise Suzuki-Miyaura reaction to afford a wide range of ortho-functionalized arylpyrimidines amenable to physical and biological evaluations.

  A concise and practical Cu-catalyzed protocol for the preparation of chloro- and bromoarenes via C–H bond activation has been developed. The advantages of this strategy are the employment of cheap Cu(NO3)2·3H2O, LiX and O2, and its compatibility with both electron-donating and electron-withdrawing substituents on aryl rings.

  Moreover, the CO and CO2 generated could be further utilized directly. Thus, chlorine-containing hydrocarbon waste, including mixed waste, can serve as chlorination reagents that neither generate hazardous by-products nor involve specialty chlorination reagents. This tandem catalytic approach represents a promising method for the viable management of a wide and diverse range of chlorine-containing hydrocarbon

  氯化化合物无处不在。然而，由于垃圾填埋和焚烧等常规处理方法不适用，含氯废物的积累会对人类健康和环境产生负面影响。在这里，我们报告了一种基于铜和钯催化剂以及 NaNO 3促进剂的可持续方法，用于对含氯碳氢化合物废物进行增值，包括固体（氯化聚合物）和液体（氯化溶剂）。在此过程中，废物在 N 导向芳烃存在下被氧化释放出氯，从而获得有价值的芳基氯化物，例如 FDA 批准的药物 vismodegib。剩余的烃组分被矿化以提供CO、CO 2和H 2 O。此外，产生的CO和CO 2可以进一步直接利用。因此，含氯烃废物，包括混合废物，可以用作氯化试剂，既不会产生危险的副产物，也不涉及特种氯化试剂。这种串联催化方法代表了一种有前途的方法，可以有效管理各种含氯烃废物。
