Among all metathesis reactions known to date in organic chemistry, the metathesis of multiple bonds such as alkenes and alkynes has evolved into one of the most powerful methods to construct molecular complexity. In contrast, metathesis reactions involving single bonds are scarce and far less developed, particularly in the context of synthetically valuable ring‐closing reactions. Herein, we report
在迄今为止有机化学中已知的所有复分解反应中,诸如烯烃和炔烃之类的多个键的复分解已发展成为构建分子复杂性的最有效方法之一。相比之下,涉及单键的复分解反应很少,而且发展还很不充分,特别是在具有合成价值的闭环反应的情况下。在这里,我们报道了脂肪族醚的铁催化开环复分解反应,用于合成取代的四氢吡喃和四氢呋喃,以及吗啉和多环醚。这种转变是通过简单的铁催化剂实现的,并且可能会通过环状氧鎓中间体进行。
