| titleOfInvention | A method for preparing moxifloxacin intermediate (S,S)-2,8-diazabicyclo[4,3,0]nonane |
| abstract | The invention provides a method for preparing moxifloxacin intermediate (S,S)-2,8-diazabicyclo[4,3,0]nonane, and relates to the technical field of organic synthesis. The method firstly performs asymmetric hydrogenation catalysis on methyl 2-chloromethyl nicotinate to obtain an intermediate with high chiral purity, without chiral resolution, and then directly through ammonolysis, reduction and cyclization to obtain moxisa Star intermediate (S,S)-2,8-diazabicyclo[4,3,0]nonane. The method provided by the invention does not need to carry out chiral resolution, the process is simple, the process steps are short, the cost is low, the chiral purity of the product is high, and the total yield is high. |
