Revisitation of the Preparation of ( S, S)‐2,8‐Diazabicyclo[4.3.0]nonane Through Enzymatic Resolution.
Abstract A chemo‐enzymatic route for the preparation of ( S , S )‐2,8‐diazabicyclo[4.3.0]nonane, a key chiral intermediate of Moxifloxacin, has been evaluated and improved. The activity of immobilized Candida antarctica lipase B was found to be increased four times for the selective hydrolysis of ci...
