Intramolecular conjugate addition reactions of 4,4-disubstituted-2,5-cyclohexadien-1-ones are described within the context of possible approaches to manzamine A. Amine 4 provided tricycle 6, with improper relative stereochemistry for use in an approach to manzamine A. Carbamates 25 and 38 gave perhydroindoles 26 and 28b under conditions of thermodynamic control, respectively, with the proper relative
在可能的甘露糖胺A方法的背景下描述了4,4-二取代-2,5-环己二烯-1-酮的分子内共轭加成反应。胺4提供了三轮车6,相对立体化学不适用于甘露糖胺A。氨基甲酸酯25和38在热力学控制条件下分别得到过氢吲哚26和28b,其中甘露糖胺A需要适当的相对立体化学;氨基甲酸酯25在热力学控制条件下得到非对映体过氢吲哚27。
