The first synthetic route to the tricyclic core of the dictyosphaeric acids has been established starting from readily available (S)-(-)-4-(tert-butyldimethylsilyloxy)cyclohexenone and involving 9 steps, including a ring-closing metathesis to produce a 13-membered macrolactone, and a doubly tethered intramolecular Michael addition.
从容易获得的(S)-(-)-4-(叔丁基二甲基硅氧基)环己烯酮出发,已经建立了通往盘状球酸三环核心的第一条合成路线,该路线包含9步反应,包括用于生成一个13元大环内酯的闭环复分解反应,以及一个双连接的分子内迈克尔加成反应。
