Tandem bicycle: In the title reaction double bonds created during ring‐closing metathesis isomerize to generate reactive iminium intermediates that undergo intramolecular cyclization reactions with tethered heteroatom and carbon nucleophiles. In this way, a series of biologically interesting heterocyclic compounds can be made, including a known precursor for the total synthesis of the antiparasitic
串联自行车:在标题反应中,在闭环易位过程中产生的双键异构化,生成反应性亚胺基中间体,这些中间体与束缚的杂原子和碳亲核试剂进行分子内环化反应。以此方式,可以制备一系列生物学上令人感兴趣的杂环化合物,包括用于抗寄生虫天然产物毒品的全合成的已知前体。
