A short stereoselective preparation of havanensin-type limonoid models is reported. The synthesis is based on a radical domino reaction of an epoxyketone to a bicyclic hydroxyketone, and is achieved in six and nine steps from simple cyclohexenones. The epoxyhavanensin derivatives show significant antifeedant activity against Spodoptera littoralis and Spodoptera frugiperda, and the epoxyketone 21 shows
报道了哈弗菌素型柠檬苦素模型的短期立体选择性制备。该合成基于环氧酮与双环羟基酮的自由基多米诺反应,并且从简单的环己烯酮分六步和九步完成。环氧havanensin衍生物对斜纹夜蛾和frugiperda有显着的拒食活性,环氧酮21对蝗虫有显着的拒食活性。
