  通过卤素诱导的环化反应从叔丁基烯丙基氨基甲酸酯直接合成恶唑烷-2-酮

  摘要：

  成功开发了一种新的合成途径，涉及2-恶唑烷酮衍生物，涉及卤代叔丁基烯丙基（苯基）氨基甲酸酯的卤素诱导的环化反应。为了优化反应，在不同的反应条件下对各种卤化试剂进行了评估。有趣的是，对于所有氯代，溴代和碘代化合物，已经完全建立了在脂肪族部位含有一个卤素原子或在对位上的芳基中取代了两个卤素原子（包括多余的卤素原子）的2-恶唑烷酮衍生物的合成路线。卤代未取代的芳基恶唑烷酮或p通过选择合适的卤化试剂和反应条件，例如反应时间和温度，可以选择性地制备-卤代-芳基恶唑烷酮。通过使用这种开发的方法成功地合成了商业化的抗抑郁药托洛沙酮。

  A simple, sustainable, efficient, mild, and low‐cost protocol was developed for d‐glucose‐assisted Cu‐catalyzed Ullmann reactions in water for amides, carbamates, and nitrogen‐containing heterocycles. The reaction was compatible with diverse aryl/heteroaryl iodides, giving highly substituted pyridine, indole, or indazole rings. This method offers an attractive alternative to existing protocols, because
