A new method of enantioselective synthesis of (S,S)-2,8-diazobicyclo [4.3.0] nonane was found by using (R)-2-amino-2- phenyl-ethanol as chiral induction reagent. The entire synthetic process included 8 steps which were easy to operate with high yield. The purification method was only simple recrystallization or even used directly in the next step without further purification. The total yield was 29%.
以(R)-2-氨基-2-苯基乙醇为手性诱导试剂,发现了一种对映选择性合成(S,S)-2,8-二氮杂双环[4.3.0]壬烷的新方法。整个合成过程包括 8 个步骤,操作简单,收率高。纯化方法只是简单的重结晶,甚至直接用于下一步,无需进一步纯化。总产率为 29%。
