An asymmetric synthetic approach to the octahydrofuro[3,4-]pyridine framework of marine natural product zamamiphidin A has been described. The key steps include an asymmetric Michael addition of ()--butanesulfinyl imidate with enamidomalonate to install the C10 stereocenter, an intramolecular alkoxide exchange/Michael addition/hydrogenation sequence to construct the bicyclic ring system.
已描述了一种用于海洋天然产物扎马米菲定A的八氢呋喃并[3,4 -]吡啶骨架的不对称合成方法。关键步骤包括()-丁烷亚磺酰亚胺与烯酰胺丙二酸酯的不对称迈克尔加成以构建C10立体中心,以及分子内醇盐交换/迈克尔加成/氢化序列以构建双环体系。
