good yield. Arylation of the above mesomeric anions followed by hydrolysis afforded 2-arylcyclohex-2-enones in addition to substituted biphenyls. A new and efficient synthesis of the male sex attractant of the Douglas Fir Tussock Moth, (Z)-heneicosa-6-en-11-one is described using the above methodology.
在液体氨中由1-甲氧基环己-1,4-二烯,1-甲氧基-5-甲基环己-1,4-二烯和1-甲氧基-4-甲基环己-1,4-二烯与酰胺钾生成的介观阴离子容易地烷基化,并且将得到的二烯水解以良好的产率产生2-烷基-,2,3-二烷基和2,4-二烷基-环己基-2-烯酮。上述中消旋阴离子的芳基化,然后水解,除了取代的联苯以外,还提供了2-芳基环己-2-烯酮。使用以上方法描述了道格拉斯冷杉Tu蛾(Z)-heneicosa-6-en-11-one的雄性引诱剂的新的有效合成方法。
