prepare chalcogen-functionalized isoxazolines. The strategy involves the reaction of β,γ-unsaturated oximes with electrophilic selenium and tellurium species, affording 19 new selenium- and tellurium-containing isoxazolines in good yields after 1 h at room temperature. The method was efficiently extended to the synthesis of 5 new (bis)isoxazoline ditellurides. One of the prepared compounds, 3-phenyl-5
在这里,我们描述了一种制备硫族元素官能化的异恶唑啉的新策略。该策略涉及β,γ-不饱和肟与亲电子硒和碲物种的反应,在室温下放置1 h后,以良好的收率提供19种新的含硒和碲的异恶唑啉。该方法有效地扩展到5种新的(双)异恶唑啉二碲化物的合成。与参考药物塞来昔布相比,所制备的化合物之一3-苯基-5-((苯基硒基)甲基)-异恶唑啉显示出更好的抗炎和抗水肿作用。
