development of concise methods for the synthesis of small functionalised spirocyclic molecules is important in the search of new bioactive molecules. To contribute this, here we represent a diastereoselective oxa-hetero-Diels–Alder reaction for the synthesis of novel spiro indanone fused pyrano[3,2-c]chromene derivatives and studied their in vitro anticancer activities. Using previously less explored cyclic
开发用于合成小的功能化螺环分子的简明方法对于寻找新的生物活性分子很重要。为此,我们在这里代表了一种非对映选择性氧杂-杂-Diels-Alder 反应,用于合成新型螺茚满酮稠合吡喃并[3,2- c ]色烯衍生物,并研究了它们的体外抗癌活性。使用以前较少探索的环酮,即茚满-1,3-二酮和3-乙烯基-2 H-色烯衍生物,我们在“类药物”分子和天然产物之间的界面处获得了新型螺杂环骨架。各种螺茚满酮稠合吡喃[3,2- c在 120 °C 回流条件下,使用 4 Å MS 作为添加剂,在甲苯中以高产率(高达 85%)合成了具有四元立体中心的 ]色烯衍生物,具有优异的非对映选择性。这些化合物对 MCF-7(乳腺癌)、HCT-116(结肠癌)、H-357(口腔癌)、MD-MB-231(乳腺癌)细胞系的体外细胞毒性研究通过 MTT 3- (4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四唑}体外测定。筛选结果显示,与商业抗癌药物
