Convenient syntheses of some analogs of the sex pheromone of citrus mealybug, planococcus citri (Risso)
A series of structural analogs (4a-h) of (+)-cis-(1R)-3-isopropenyl-2,2-dimethylcyclobutanemethanol acetate, the sex pheromone of citrus mealybug, Planococcus citri (Risso), was synthesized from (+)-α-pinene(1) via intermediate, (+)-cis-(1R)-2,2-dimethyl-3-acetylcyclobutaneethanol(2).
