We describe herein a short and efficient synthesis of the C1-C9 fragment of the potent antitumor agent dictyostatin. Notable features of this approach include a Sharpless asymmetric epoxidation followed by epoxide opening under Myashita's conditions to introduce the stereogenic centers at C6 and C7, and a Horner-Wadsworth-Emmons type reaction under Ando's conditions to construct the Z-double bond of
我们在本文中描述了有效的抗肿瘤药dictyostatin的C1-C9片段的短而有效的合成。这种方法的显着特征包括:在Myashita条件下进行Sharpless不对称环氧化,然后环氧化物打开,以在C6和C7处引入立体异构中心;在Ando条件下,进行Horner-Wadsworth-Emmons型反应,以构建1的Z-双键3-(Z,E)-二烯体系。
