RESUMEN
The citrus mealybug, Planococcus citri (Risso) is a common pest in the Southern U. S. and the Mediterranean. Two alternative syntheses of the female sex pheromone, (1R)-(+)-cis-2,2-dimethyl-3-isopropenyl-cyclobutane methanol acetate, have been developed. Key transformations include an allylic oxidation of (1R)-(+)-alpha-pinene to (+)-R-verbenone, oxidative decarboxylation using RuCl(3)-NaIO(4), and methylenation with Zn/CH(2)Br(2)/TiCl(4).
