(8R) and (8S)-Hydroxy-6-methyl-5,6,7,8-tetrahydrodibenz[c,e]azocines (R- and S-1) were synthesized by oxidative kinetic resolution of N-(2-iodobenzyl)-β-(2-iodophenyl)ethanolamine (8), followed by cyclization of the optically active acetates (R- and S-6) of R- and S-8 with zero-valent nickel to (8R)- and (8S)-acetoxyazocines (R- and S-7), and by hydrolysis of the acetates (R- and S-7).
通过N-(2的氧化动力学拆分,合成了(8 R)和(8 S)-羟基-6-甲基-5,6,7,8-四氢二苯并[ c,e ]偶氮素(R-和S - 1)。-碘苄基)-β-(2-碘苯基)乙醇胺(8),然后将具有零价镍的R-和S - 8的旋光乙酸酯(R-和S - 6)环化为(8 R)-和(8 S)-乙酰氧基偶氮素(R-和S - 7),以及通过乙酸盐的水解(R-和S - 7)。
