employed successfully to access two different natural products bearing two contiguous stereogenic centers. As a result, first chiron approach to formal total synthesis of an amide alkaloid, (4R,5R,2E)-4,5-dihydroxy-1-(piperidin-1-yl)dec-2-en-1-one and total synthesis of a male sex pheromone in parasitic Hymenoptera, (4R,5R)-(-)-5-hydroxy-4-decanolide have also been achieved.
(3R,4S,5R)-(-)-3,5-dihydroxy-4-decanolide的一种简短,简单且方便的Chiron方法,已报道的天然产乙酸原素((+)-polyporolide)结构的迄今未知的非对映异构体从市售的廉价手性池分子D-(+)-甘露醇开始,已在九个有效步骤中完成了本发明。为此目的,由D-(+)-甘露醇分6步合成的高级中间体被成功地用于获得带有两个连续立体中心的两种不同天然产物。结果,第一种凯隆方法正式合成了酰胺生物碱,(4R,5R,2E)-4,5-二羟基-1-(哌啶-1-基)癸-2-烯-1-酮和总(4R,5R)-(-)-5-羟基-4-癸醇化物的寄生性膜翅目中雄性信息素的合成也已实现。
