Ezetimibe intermediate, synthesis method of intermediate and synthesis method of ezetimibe

The invention provides an ezetimibe intermediate, a synthesis method of the intermediate and a synthesis method of ezetimibe. The method is short in synthetic route. The method includes the steps of making fluorobenzene as the initial raw material sequentially have acylation reaction with glutaric anhydride and 4(S)-4-phenyl oxazolidinone to generate a compound II, protecting carbonyl through 2,2-bis-substituted-1,3-propylene glycol to obtain a compound III, generating a compound V through the compound III and a compound IV under the catalysis of titanium tetrachloride, cyclizing the compound V to generate a compound VI, hydrolyzing the compound VI to obtain a compound VII, and reducing the compound VII through a borane chiral reducing agent and removing a benzyl protecting group in a hydrogenated mode to obtain the ezetimibe. The method is high in yield, little in side reaction and suitable for industrial mass production.
