  摘要：

  在我们对真菌嘌呤转运蛋白的研究过程中，基于嘌呤底物与构巢曲霉FcγB载体的相互作用，合理地设计了许多新的3-脱氮嘌呤类似物，并按照有效的合成程序进行了合成。已经发现某些衍生物特异性抑制FcγB介导的[ 3 H]-腺嘌呤摄取。已经进行了分子模拟，表明所有活性化合物都通过与Asn163形成氢键与FcyB相互作用，而在3- deazaadenine的9和N 6位插入疏水片段增强了抑制作用。

  effective for a wide range of arenes, including nonactivated arenes bearing simple functionalities such as fluoride, chloride, ester, amide, ether, nitrile, and trifluoromethyl groups as well as heteroarenes including indole, thiophene, pyridine, and isoquinoline. An analogous C-H azidation is also accomplished using azidoiodinane for direct introduction of a useful azide group onto a broad scope of arenes

  芳烃胺化是通过位点选择性 CH 锌化，然后在温和条件下铜催化与 O-苯甲酰羟胺偶联来实现的。这一成功的关键是由氨基二乙基锌酸锂介导的邻位锌化，它对多种芳烃有效，包括带有简单官能团的非活化芳烃，如氟化物、氯化物、酯、酰胺、醚、腈和三氟甲基以及杂芳烃包括吲哚、噻吩、吡啶和异喹啉。类似的 CH 叠氮化也可以使用叠氮碘来完成，将有用的叠氮基团直接引入到广泛的芳烃和杂芳烃上。这些新的转化提供了快速获得有价值且多样化的氨基芳烃化学空间的途径。通过后期胺化和叠氮化反应合成天然产物 (-)-尼古丁和抗抑郁药舍曲林的新型类似物，证明了它们在有机合成和药物发现中的广泛应用。
