Since its isolation in 1991, the polyazole natural product thiangazole has become a popular target for total synthesis due to its challenging array of heterocyclic segments and its reported potent antiviral activity. The synthetic activity toward thiangazole is reviewed and a novel approach that takes advantage or aziridine and oxazoline intermediates en route to thiazolines is presented.
自1991年分离以来,多氮杂环
天然产物硫氮唑已成为全合成的热门目标,因其拥有复杂的杂环片段以及报告显示的强效抗病毒活性。本文回顾了针对
硫氮唑的合成活动,并提出了一种新颖的方法,该方法利用了在合成
硫唑啉过程中使用的氮杂环和
噁唑烯中间体。
