Category: esters-buliding-blocksIn 2022 ,《A Novel Trisubstituted Tetrahydropyran as a Possible Pheromone Component for the South American Cerambycid Beetle Macropophora accentifer》 was published in Journal of Chemical Ecology. The article was written by Silva, Weliton D.; Zou, Yunfan; Hanks, Lawrence M.; Bento, Jose Mauricio S.; Millar, Jocelyn G.. The article contains the following contents:
A novel trisubstituted tetrahydropyran was isolated and identified from the sex-specific volatiles produced by males of the cerambycid beetle Macropophora accentifer (Olivier), a serious pest of citrus and other fruit crops in South America. The compound was the major component in the headspace volatiles and it was synthesized in racemic form. However, in field trials, the racemate was only weakly attractive to beetles of both sexes, suggesting that attraction might be inhibited by the presence of the “”unnatural”” enantiomer in the racemate. Alternatively, the male-produced volatiles contained a number of minor and trace components, including a compound tentatively identified as a homolog of the major component, as well as a number of unsaturated 8-carbon alcs. and aldehydes. Further work is required to conclusively identify and synthesize these minor components, to determine whether one or more of them are crucial components of the active pheromone blend for this species. The results came from multiple reactions, including the reaction of Ethyl 3-oxopentanoate(cas: 4949-44-4Category: esters-buliding-blocks)
Ethyl 3-oxopentanoate(cas: 4949-44-4) belongs to ketone compounds. They are most widely used as solvents, especially in industries manufacturing explosives, lacquers, paints, and textiles. Ketones are also used in tanning, as preservatives, and in hydraulic fluids.Category: esters-buliding-blocks
