isolated from the stony coral Montipora sp., was shown to exhibit cytotoxicity against certain solid tumor cells. Construction of a suitably functionalized α,β-unsaturated lactam for palladium-catalyzed couplings was realized via a Beckmann rearrangement. Subsequent Sonagoshira coupling with a known alkyne chain efficiently afforded the alleged structure of the natural product.
Montiporyne E 是一种从石珊瑚 Montipora sp. 中分离出来的新型二乙炔内酰胺,已显示出对某些实体瘤细胞的细胞毒性。通过贝克曼重排实现了用于钯催化偶联的适当功能化的 α,β-不饱和内酰胺的构建。随后的 Sonagoshira 与已知的炔烃链偶联有效地提供了所谓的天然产物结构。
