  摘要：

  RET激酶的致癌激活已在多种肿瘤疾病中发现，如甲状腺髓样癌，多发性内分泌肿瘤，甲状腺乳头状癌和非小细胞肺癌。目前批准的RET抑制剂最初并未设计为RET抑制剂，而且它们对RET激酶的效能尚未优化。因此，需要能够抑制野生型RET（wt RET）及其突变体（例如V804M RET）的新型化合物。本文中，我们介绍了新型亚微摩尔wt RET / V804M RET抑制剂N-（2-氟-5-三氟甲基苯基）-N'-{4'-[（2''-苯甲酰胺基）吡啶的开发和初步评估从我们先前鉴定的4-苯胺基嘧啶命中化合物开始，具有4-苯胺基吡啶结构的-4”-基氨基]苯基}脲（69）。

  ortho-selective C–H halogenation methodology is reported herein. The highlight of the work is the highly selective C(sp2)–H functionalization of benzyl nitriles in the presence of activated C(sp3)–H bond, which results in good yields of the halogenated products with excellent regioselectivity. Along with benzyl nitriles, aryl Weinreb amides and anilides have been evaluated for the transformation using aprotic

  [reaction: see text] Copper-mediated cross-coupling reactions of sulfoximines with aryl iodides and aryl bromides provide N-arylated sulfoximines in high yields. The method is complementary to the known palladium-catalyzed N-arylation and allows the preparation of N-arylated sulfoximines, which have previously been inaccessible.

  Carbazoles were successfully synthesized by oxidative cyclization of the corresponding diaryl derivatives using electrochemically generated hypervalent iodine oxidant. Electron-withdrawing nitro and donating methoxy groups at the para position of the acetamide group interfered with cyclization. Glycozoline (8) was successfully synthesized in five steps with 50% overall yield.
