A metal-free and mild approach for constructing 5-amino-1,2-selenazole skeletons by NBS/KSeCN-mediated N-selenocyanation and nucleophilic cyclization of β-enaminones has been developed. Various isoselenazole compounds and the isoselenazolyl derivatives of anti-inflammatory medicines, including isosepac, oxaprozin, and ibuprofen, have been obtained with good yields. This efficient, “one-pot”, and atomic
开发了一种通过 NBS/KSeCN 介导的N-硒氰化和 β-烯胺酮亲核环化构建 5-氨基-1,2-硒唑骨架的无金属且温和的方法。各种异硒唑化合物和抗炎药物的异硒唑基衍生物,包括异塞帕克、奥沙普秦和布洛芬,已获得良好的产率。这种高效、“一锅”和原子经济策略可能代表了通过“ + SeCN”途径构建1,2-硒唑框架的另一种途径,并为含有Se-N键的杂环提供了新的途径。
