| titleOfInvention | Synthesis method of monofluoro spiro compound and intermediate thereof |
| abstract | The invention provides a synthesis method of a monofluoro spiro compound and an intermediate thereof, the monofluoro spiro compound is prepared by oxidizing, reducing, eliminating, fluorinating and subsequent dehydration steps of a spiro compound II, compared with the prior art of direct fluorination by taking hydroxyl as a precursor, the synthesis method avoids the generation of a cyclic internal olefin by-product, and has simple preparation, separation and purification operations and stable process. |
