该中间体在本合成路线中的序号:(III)Synthesis of the iodopropionic intermediate (IV) is achieved as follows. The condensation of 4-benzyloxy-3,5-dichlorobenzoic acid (I) with L-serine benzyl ester (II) by means of BOP and TEA in dichloromethane gives the benzoyl-serine (III), which is then converted into the target iodopropionic intermediate (IV) by reaction with MsCl and TEA, followed by treatment with NaI in acetone.
