摘要
2,6,6-Trimethyl-2-azaspiro[4.4]nonane-1,3-dione (9), a spirosuccinimide moiety of asperparaline A (1), was synthesized by starting from 2,2-dimethylcyclopentanone (4) via trinitrile 6 in five steps in a moderate yield. This conversion establishes a model study for synthesis of the spirosuccinimide moiety of asperparaline A (1).
