| titleOfInvention | Preparation method of bimatoprost drug intermediate |
| abstract | The invention relates to the technical field of synthesis of medical intermediates, in particular to a preparation method of a bimatoprost medical intermediate, which takes a compound I as a raw material to react with a compound II under the action of alkali to obtain the bimatoprost medical intermediate: (3aR,4R,5R,6aS) -5- (benzoyloxy) hexahydro-4- [ (1E) -3-oxo-5-phenyl-1-pentenyl ] -2H-cyclopenta [ b ] furan-2-one. The preparation method has the advantages of easily obtained raw materials, higher stereoselectivity, higher yield and purity, and is easier for the industrial production of the intermediate of the bemepiridine medicine. |
