building block for introduction of the C+D ring motif of steroids to prepare series of novel secosteroids containing nitrile or disulfide functionalities. Key steps in synthesis of these novel steroid analogues are palladium-catalyzed cross-coupling reactions. All target compounds were characterized by comprehensive analysis; in particular the stereochemical assignments of dinitriles 12a and 12b could be
Grundmann的酮(3)被用作引入类固醇C + D环基序的通用构件,以制备一系列含有腈或二硫键功能的新型类固醇。合成这些新型类固醇类似物的关键步骤是钯催化的交叉偶联反应。通过全面分析对所有目标化合物进行了表征;尤其是二腈12a和12b的立体化学分配可以通过NMR实验进行。最初通过细胞毒性试验证实了所有化合物的药理潜力。
