Preparation and assignment of absolute configurations to both enantiomers of the sex pheromone of the longtailed mealybug, an irregular monoterpenoid with extraordinary biological activity, has been completed. Comparison of the biological activities of both enantiomers and the racemate in field trials showed that the (S)-(+)-enantiomer was highly attractive to male mealybugs, strongly suggesting that
长尾粉虱(一种具有异常生物学活性的不规则单萜类)的性信息素的两个对映异构体的绝对构型的制备和分配均已完成。对映异构体和外消旋体的生物学活性在田间试验中的比较表明,(S)-(+)-对映体对雄性粉虱极具吸引力,强烈表明雌性长尾粉虱产生了这种对映体。(R)-(-)-对映异构体是良性的,既没有吸引力也没有抑制作用。
