Reaction of methylenecyclopentanones2 with alkyl iodides via radical 1,4-addition pathway proceeds in good yields, thus providing an easy method for synthesis of not only known prostaglandins such as PGE1 and Limafrost but also new prostaglandin derivatives.
亚甲基环戊酮2通过自由基1,4-加成途径与烷基碘的反应以良好的收率进行,因此不仅为已知的前列腺素(如PGE 1和利马弗罗斯特)而且为新的前列腺素衍生物的合成提供了简便的方法。
