A new stereocontrolled route to conjugated dienynes is described, utilising organometallic addition to pyrylium salts followed by Wittig homologation and dehydrohalogenation. The utility of this methodology is illustrated in the first total synthesis of the marine metabolite Carduusyne A.
描述了一种新的通过立体控制的方法制备共轭二烯的方法,该方法利用有机金属添加至吡喃鎓盐中,然后进行Wittig同源化和脱卤化氢。海洋代谢产物Carduusyne A的第一个全合成中说明了该方法的实用性。
