Synthesis of the 5'-fluoro-2'-β-methyl analogues of neplanocin was carried out. Key intermediate cyclopentenone 19 was prepared from methyl α-D-mannopyranoside by a new approach consisting of ring-closing metathesis, stereoselective introduction of the 2'-methyl group, and intramolecular oxyselenenylation of the double bond as representative steps. Subsequent introduction of a fluorine atom at the
进行了 neplanocin 的 5'-氟-2'-β-甲基类似物的合成。关键中间体环戊烯酮 19 是由甲基 α-D-吡喃甘露糖苷通过闭环复分解、2'-甲基的立体选择性引入和双键的分子内氧化硒化等新方法制备的。随后在 19 的 5'-位引入氟原子通过使用 Selectfluor 的亲电氟化进行。
