An alkene (1) is added to cyclopentenone (2) under the action of an alkyl lithium and an organic copper reagent to form an adduct, said adduct is reacted with e.g. a carboxylic anhydride (4) to obtain a prostaglandin derivative (6), which is then treated with a nitrogen-containing compound such as 2,2′-bipyridyl to efficiently remove the organic copper reagent used in the synthesis and by-products derived from said reagent, to obtain a purified prostaglandin derivative (6) having a high purity:
烯烃(1)在烷基锂和有机铜试剂的作用下加到环戊酮(2)上,形成一个加合物,所述加合物与例如羧酸酐(4)反应,得到一个前列腺素衍生物(6),然后用含氮化合物如2,2′-联吡啶处理,以高效地去除合成中使用的有机铜试剂及由该试剂衍生的副产物,从而获得具有高纯度的纯化前列腺素衍生物(6)。
