acid catalyzed reaction of the bicyclic acetal with allyltrimethylsilane introduces the side chain (as yet unfunctionalized) and sets the stereogenic centers at the tetrahydro-2H-pyran ring of the pederin moiety.
基于二羟基醛5或环氧乙烷丁醛6制备类型3的双环缩醛衍生物(参见方案2)。路易斯酸催化的双环乙缩醛与烯丙基三甲基硅烷的反应引入了侧链(尚未官能化),并将立体异构中心设置在pederin部分的四氢-2 H-吡喃环上。
