  摘要：

  提出了通过5 -exo-dig法合成各种恶唑啉和恶唑的N-炔丙基酰胺的无金属环化。使用（二乙酰氧基碘）苯（PIDA）作为反应促进剂和碘化锂（LiI）作为碘源，N-炔丙基酰胺的分子内碘加氧反应很容易进行，从而导致相应的（E）-5-碘亚甲基-2-恶唑啉优良的孤立产量。此外，使用PhI（OAc）2 / LiI系统，N在氧气存在下，在可见光照射下，可以将-炔丙基酰胺转化为相应的恶唑-5-甲醛。简单衍生化后，所得产物可进一步转化为各种恶唑啉和恶唑衍生物，该方法最终提供了通往多种生物活性结构的有效途径。

  Novel catalytic systems consisting of cationic gold complexes, N-hydroxyphthalimide (NHPI), and transition-metal-based Lewis acids have been developed for the one-pot synthesis of functionalized oxazoles from N-propargylamides with excellent functional group tolerance. These transformations demonstrated the excellent compatibility of homogeneous gold catalysis with organocatalytic oxidative carbon–nitrogen

  Dihydropyrimidin-4-ones were efficiently synthesized from copper catalyzed reaction between N-(prop-2-yn-1-yl)amides and sulfonylazides under mild conditions in moderate to excellent yields (up to 96% yields). The cascade process involves the copper-catalyzed alkyne–azide cycloaddition, the formation of ketenimine intermediate, the intramolecular nucleophilic addition of ketenimine, and subsequent

  alkynes by gold(III) hydride complexes [(C^N^C)AuH] was found to be mediated by radicals and proceeds by an unexpected binuclear outer‐sphere mechanism to cleanly form trans‐insertion products. Radical precursors such as azobisisobutyronitrile lead to a drastic rate enhancement. DFT calculations support the proposed radical mechanism, with very low activation barriers, and rule out mononuclear mechanistic
