Methyl-eugenol

By methylation with dimethyl sulphate and potash, it yields methyl-eugenol, boiling at 248° to 249° and which on oxidation yields veratric acid, melting at 179° to 180°. [Pg.261]

The diphenylurethane melts at 107° to 108°. By treatment with methyl iodide in the presence of caustic alkali, eugenol is converted into methyl-eugenol, which is characterised by its monobromo derivative melting at 79° to 80°. [Pg.261]

The principal derivative for identification purposes is veratric acid, C H.,(C00H)(0CH3)2, which is obtained by oxidising 6 grams of methyl-eugenol with a solution of 18 grams of potassium permanganate in 400 c.c. of water. When recrystallised from alcohol, veratric acid melts at 179° to 180°. [Pg.263]

Methyl-isoeugenol, CjiHj O, bears exactly the same relationship to isoeugenol as methyl-eugenol does to eugenol. It occurs naturally in the oil of Asarum arifolium, and can be obtained by the action of methyl iodide on isoeugenol sodium, or by isomerising methyl-eugenol by hot alcoholic potash. [Pg.264]

Pharmacophagy of methyl eugenol (ME), a highly potent male attrac-tant, by the fruit Bactrocera papayae, results in the hydroxylation of ME to sex pheromonal components, 2-allyl-4,5-dimethoxyphenol (DMP) and (E )-coniferyl alcohol (CF). ... [Pg.291]

Dr. Chambers has written an excellent review article on "Attractants for Fruit Fly Survey and Control" (5 ). In this review. Chambers discusses the development of parapheromones and food baits and the implementation of these attractants. Thousands of compounds were screened in Hawaii and in Mexico during the period of 1950 to 1955 (6), and this screening process yielded some promising candidates. Methyl eugenol, proposed by Steiner in 1952 (X), remains the most effective lure for the Oriental fruit fly. Cue lure, found by Beroza in 1960 (8), is a good lure for the melon... [Pg.433]

Methyl eugenol 013,4-dimethoxy-l-allylbenzene [95-15-2] was fust characterized in 1915 as a powerful attractant for the male oriental fruit fly, Dams dorsalis, and attracts at least 60 other closely related Dams spp. Raspberry ketone [5471-51-2] or l-(4-/>-hydroxyphenyl)-2-butanone [5471-51-2] (174) is an equally powerful attractant for the melon fly, Dams mmrbitae, and the Queensland fmit fly, D. tryoni, and at least 180 other closely related Dams spp. The acetyl ester (cue-lure) (175) is more volatile and is a synthetic parakairomone especially effective for monitoring infestations by these species. Methyl eugenol and cue-lure [3572-06-3] have been used successfully in "male annihilation" of the oriental fmit fly and the melon fly by applying them to fiber board blocks or pieces of twine together with malathion or naled insecticides and distributing them over infested areas at doses of 15 g of attractant and 1 g of the insecticide per ha. [Pg.308]
