structure. The total synthesis of a reported natural product, 3′-hydroxymethylrocaglate (5), was achieved using [3 + 2] cycloaddition between 3-hydroxyflavone and methyl cinnamate. We also describe the synthesis of rocaglamide heterocycle derivatives and evaluate their Wnt signal inhibitory activities. Compounds 4, 5, 22a, 22b, 22c and 23c showed potent Wnt signal inhibitory activity.
乐卡格酰胺是具有环戊[ b ]苯并呋喃核心结构的生物活性天然化合物。使用3-羟基黄酮和肉桂酸甲酯之间的[3 + 2]环加成反应,可以完成报告的天然产物3'-羟甲基rocaglate(5)的总合成。我们还描述了rocaglamide杂环衍生物的合成,并评估其Wnt信号抑制活性。化合物4,5,图22A,22B,22C和23C显示了强的Wnt信号的抑制活性。
