The concise, stereocontrolled syntheses of DAB-1 and d-fagomine were achieved utilizing chiral oxazine. The key features in these strategies are the stereoselective intramolecular oxazine formation catalyzed by palladium(0), and pyrrolidine and piperidine formation by catalytic hydrogenation of oxazine.
利用手性恶嗪实现了DAB-1和d - fagomine的简洁,立体控制的合成。这些策略的关键特征是钯(0)催化的立体选择性分子内恶嗪的形成,以及恶嗪的催化加氢形成吡咯烷和哌啶。
