合成路线1
该中间体在本合成路线中的序号：(I)Beckmann rearrangement of oxime (I) in the presence of p-acetamidobenzenesulfonyl chloride and pyridine afforded acetamide (II). Subsequent fluorination of (II) using perchloryl fluoride produced fluoroenamide (III), which was hydrolyzed with HCl to give fluoroketone (IV). After treatmentof (IV) with o-phenylenephosphorochloridite (V) and pyridine, the intermediate phosphite ester (VI) was converted to iodide (VII) by means of iodine in CH2Cl2. Finally, reductive deiodination of (VI) with Zn in AcOH produced the target compound.
