合成路线1
该中间体在本合成路线中的序号：(II)5-Chloromercuri-2'-deoxyuridine (II) is prepared from 2'-deoxyuridine (I) by reaction with mercuriacetate and natrium chloride (1). Condensation of (II) with ethylacrylate (A) and lithium palladium chloride gives (E)-5-(2-carbethoxyvinyl)-2'-deoxyuridine (III), which is readily hydrozyled to (E)-5-(2-carboxyvinyl)-2'-deoxyuridine (IV) under basic conditions (0.5M NaOH). The final step involves the reaction of (IV) with N-bromosuccinimide to produce (E)-5-(2-bromovinyl)-2'-deoxyuridine.
