Synthesis method of ticagrelor key intermediate

The invention discloses a synthesis method of a ticagrelor key intermediate, which belongs to the technical field of medical technologies, and is technically characterized by comprising the following steps: S1, dissolving a compound I in an organic solvent, adding strong base, reacting with sodium bromoacetate or bromoacetic acid, and adding ethyl chloroformate to synthesize a compound II; S2, adding sodium borohydride into the solution of the compound II in batches to obtain a compound III; and S3, deprotecting the compound III under the action of ammonium formate and 10% palladium on carbon, and then adding Ltartaric acid for salifying to synthesize a compound IV. The invention aims to provide a synthesis method of a ticagrelor key intermediate. The cost is effectively reduced, the synthesis process is simplified, and the method is suitable for large-scale production.

Method for preparing ticagrelor key intermediate

The invention relates to a chemical synthesis method of ticagrelor key intermediate 2-[[(3aR, 4S, 6R, 6aS)-6-aminotetrahydro-2,2-dimethyl-4H-cyclopenta-1,3-dioxolane-4-yl] oxy]ethanol (a key intermediate A). The method comprises the following steps: taking D-ribose as a raw material, and carrying out ten chemical reaction steps of 1-locus methylation and 2,3-loci isopropylidene protection, 4-locus derivatization, iodination, furan ring-opening, hydroxylamine reaction, palladium on carbon catalytic hydrogenation, amino Cbz protection, hydroxy protection, sodium borohydride reduction ester, Cbz removal protection and the like, thereby obtaining the key intermediate A. The raw materials are cheap and readily available, the preparation process is high in operability, steps of optical resolution, chiral induction and the like are avoided, the total yield is relatively high, and the product quality is better; particularly due to the use of sodium borohydride reduction ester, the preparation cost of ticagrelor is greatly reduced; and the method is suitable for large-scale industrial production.
