Using dehydroepiandrosterone as the starting material, we have synthesized a series of steroid analogs possessing a D-ring fused with heterocycles which are pyridine, imidazo [2,1-b]thiazoles or substituted thiazole imines. All the final structures are first reported and identified by NMR and MS spectroscopys, the yields of these products are moderate to good and the reaction conditions are mild. The
使用脱氢
表雄酮作为起始原料,我们合成了一系列具有与杂环稠合的D环的类固
醇类似物,所述杂环为
吡啶,
咪唑并[2,1-b]
噻唑或取代的
噻唑亚胺。首先报道了所有最终结构,并通过NMR和MS光谱进行了鉴定,这些产品的收率中等至良好,反应条件温和。研究了合成化合物对
EC-109(人食管癌),
EC-9706(人食管癌),MGC-803(人胃癌)的细胞毒性。
