[formula: see text] An asymmetric synthesis of (-)-slaframine and N-acetylslaframine has been accomplished starting from an enantiopure dihydropyridone building block. The oxygen-carbon bond at C-1 was incorporated with complete stereoselectivity by using an efficient phenylselenocyclocarbamation reaction.
从对映体纯的二氢吡啶酮结构单元开始已经完成了(-)-slaframine和N-乙酰基slaframine的不对称合成。通过使用有效的苯基硒代杂环氨基甲酸酯化反应,可以完全立体选择性地结合C-1处的氧碳键。
