  Desulfonylation-Initiated Distal Alkenyl Migration in Copper-Catalyzed Alkenylation of Unactivated Alkenes

  摘要：

  A novel and efficient protocol for desulfonylation-initiated distal alkenyl migration and its application to the elusive alkenylation of unactivated alkenes have been presented. This radical cascade process has successfully achieved the vicinal difluoroalkylalkenylation of unactivated alkenes with excellent chemo-, regio-, and stereoselectivity in high efficiency under mild conditions. The reactions afford previously unknown 3,3-difluoro-S-styrylpiperidin-2-one derivatives or beta-styryl-gamma-difluoroalkyl amines bearing a quaternary stereocenter. This is the first report of difunctionalization of unactivated alkenes through desulfonylation-initiated distal alkenyl migration.

• Visible-Light-Induced Direct Oxidative C−H Amidation of Heteroarenes with Sulfonamides
  作者：Kun Tong、Xiaodong Liu、Yan Zhang、Shouyun Yu

  DOI：10.1002/chem.201604014

  日期：2016.10.24

  A direct oxidative C−H amidation of heteroarenes with sulfonamides via nitrogen‐centered radicals has been achieved. Nitrogen‐centered radicals are directly generated from oxidative cleavage of N−H bonds under visible‐light photoredox catalysis. Sulfonamides, which are easily accessed, are used as tunable nitrogen sources and bleach (aqueous NaClO solution) is used as the oxidant. A variety of heteroarenes

  已经实现了杂芳烃与磺酰胺通过氮中心自由基的直接氧化CH H酰胺化反应。氮中心自由基是在可见光光氧化还原催化下，NH键的氧化裂解直接产生的。易于使用的磺酰胺用作可调氮源，而漂白剂（NaClO水溶液）用作氧化剂。包括吲哚，吡咯和苯并呋喃在内的各种杂芳烃都可以高产率（高达92％）进行酰胺化反应。这些反应具有高度的区域选择性，所有产物均被分离为单一的区域异构体。
