  Synthesis of Selenazoles by in Situ Cycloisomerization of Propargyl Selenoamides Using Oxygen–Selenium Exchange Reaction

  摘要：

  Herein, we describe an approach toward selenazole preparation based on the cycloisomerization of propargyl selenoamides. The selenoamides were synthesized in situ using the Ishihara reagent with spontaneous cyclization to form the 2,5-disubstituted selenazoles. Heterocylcles 9a-j were prepared using readily available starting materials, and yields ranged from moderate to good (20-80%). Methylselenazole 9a could be transformed into a bromomethyl derivative 13 using NBS. The intermediate 13 would provide a more versatile building block for further derivatizations, e.g., the cyanide 14.

  摘要：

  开发强大的方法以在异喹诺酮支架的N-取代基处引入多功能官能团仍然是一个巨大的挑战。在本文中，我们报道了一种新颖的三组分级联环化反应，可通过铑（III）催化的CH-H活化/环化/亲核攻击有效地构建异喹诺酮衍生物的N-氧丙基链，恶唑同时用作指导基团和潜在基团。功能化试剂。

• Merging gold catalysis, organocatalytic oxidation, and Lewis acid catalysis for chemodivergent synthesis of functionalized oxazoles from N-propargylamides

  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
