(2R,4R,6R,8R)-2,4,6,8-Tetramethyldecanoic acid and (2R,4R,6R,8R)-2,4,6,8-tetramethyldecanol, as well as the (2R,4R,6R,8R) and the (2S,4R,6R,8R) diastereomers of 4,6,8-trimethyldecan-2-ol, have been obtained from the preen-gland wax of the domestic goose.
Synthesis of Asymmetrical Methyl-Branched Chiral Ketones from the Corresponding Homologous Wax Esters. A New Synthesis of the Insect Pheromone Lardolure and of 9-Norlardolure

The insect pheromone (2R,4R,6R,8R)-4,6,8-trimethyl-2-undecyl formate (lardolure, 7c) and (2R,4R,6R,8R)-4,6,8-trimethyl-2-decyl formate (9-norlardolure, 7b) have been synthesized from the corresponding homologous chiral methyl-branched esters 1b and 1c, which have been obtained from the preengland wax of the domestic goose Anser a. f. domesticus.The intermediate (4R,6R,8R)-4,6,8-trimethyl-2-undecanone (4c) and (4R,6R,8R)-4,6,8-trimethyl-2-decanone (4b), the (2R)-alcohols 5c and 5b, as well as some analogous compounds, have been characterized. 9-Norlardolure (7b) shows a weak pheromone activity. - Keywords: Preen-gland waxes; Anser a. f. domesticus; Cairina moschata; Methyl-branched chain aldehydes, ketone, sec. alcohol; Pheromones
