• Macrolide Synthesis through Intramolecular Oxidative Cross-Coupling of Alkenes
  作者：Bing Jiang、Meng Zhao、Shu-Sen Li、Yun-He Xu、Teck-Peng Loh

  DOI：10.1002/anie.201710601

  日期：2018.1.8

  A RhIII‐catalyzed intramolecular oxidative cross‐coupling between double bonds for the synthesis of macrolides is described. Under the optimized reaction conditions, macrocycles containing a diene moiety can be formed in reasonable yields and with excellent chemo‐ and stereoselectivity. This method provides an efficient approach to synthesize macrocyclic compounds containing a 1,3‐conjugated diene

  Reported herein is a practical method for macrolactam synthesis via a Rh(III)-catalyzed ring closing alkene–alkene cross-coupling reaction. The reaction proceeded via a Rh-catalyzed alkenyl sp2 C–H activation process, which allows access to macrocyclic molecules of different ring sizes. Macrolactams containing a conjugated diene framework could be easily prepared in high chemoselectivities and Z,E
