The synthesis of a second-generation cobalt catalyst for the formation of trans-THF products via the Mukaiyama aerobic oxidative cyclization is reported. Two procedures have been developed with the new water-soluble catalyst that give superior yields and greatly simplify purification compared to the previous catalysts.
据报道,通过Mukaiyama好氧氧化环化反应合成了第二代钴催化剂,以形成反式THF产物。与以前的催化剂相比,使用这种新型水溶性催化剂开发了两种方法,它们具有较高的收率并大大简化了纯化过程。
