A divergent, three-step total synthesis of rhodonoids C and D has been achieved using a biosynthetically inspired, acid-catalyzed cascade cyclization of an epoxy-chromene that involves the presumed intermediacy of o-quinone methides. Application of a similar strategy also allowed synthesis of the alkaloid murrayakonine D.
使用生物合成方法启发性的环氧色烯酸催化级联环化反应,实现了类胡萝卜素C和D的发散,三步全合成,其中涉及到了邻醌甲基化物的中间体。应用类似的策略还可以合成生物碱MurrayakonineD。
