    • The object is to produce an azabicycloalkanol derivative, particularly a cis-3-substituted-3-azabicyclo[3.2.1]octan-8-ol derivative which is a useful intermediate for agricultural chemicals or pharmaceutical agents, with a good yield and at an industrially low cost. A diastereomer of an azabicyclo-C6-10-alkanol derivative having a methyne substituted a hydroxyl group as an asymmetric carbon (e.g., a trans-3-substituted-3-azabicyclo[3.2.1]-8-ol derivative) is isomerized in the presence of a transition metal complex, thereby producing an excess amount of a thermodynamically more stable one of diastereomers (e.g., a cis-3-substituted-3-azabicyclo[3.2.1]-8-ol derivative). In this manner, a thermodynamically more stable one of diastereomers of the azabicyclo-C6-10-alkanol derivatives can be produced.
    • 本发明的目的是制备氮杂双链烷醇衍生物,特别是作为农药或药剂的有用中间体的顺式-3-取代-3-氮杂双环[3.2.1]辛-8-醇衍生物,其产率高, 工业成本低。 具有取代羟基作为不对称碳的甲炔的氮杂双环C 6-10链烷醇衍生物的非对映体(例如,反式-3-取代-3-氮杂双环[3.2.1] -8-醇衍生物)异构化为 过渡金属络合物的存在,从而产生过量的热力学上更稳定的非对映异构体(例如,顺式-3-取代-3-氮杂双环[3.2.1] -8-醇衍生物)。 以这种方式,可以制备氮杂双环C 6-10链烷醇衍生物的非对映异构体的热力学上更稳定的一种。
