The invention relates to a compound of formula (I) or a salt thereof: wherein the substituents R1, R2, R3, R4, R5, R6, R7 and X are defined herein, its synthesis and methods of controlling and monitoring populations of mealybugs.
β-alkyl substituted γ-lactones and whiskey lactone analogues were synthesized, and the odor properties were evaluated. During the preparation of the chiral intermediates, we found good reaction conditions for the highly enantioselective esterification of 3-arylmethyl-2-methyl-1-propanols to kinetically resolve them. The results of the olfactoryevaluations of the synthesized lactones revealed that the alkyl
