Disparlure, structure

Give the structure of the alkene including stereochemistry that ] you would choose as the starting material in a preparation of synthetic disparlure J... 

Disparlure, C1 Ha 0, is a sex attractant released by the female gypsy moth, Lyman-tria dispar. The H NMR spectrum of disparlure shows a large absorption in the alkane region, 1-2 5, and a triplet at 2.8 fi. Treatment of disparlure, first with aqueous acid and then with KMnC>4, yields two carboxylic acids identified as undecanoic acid and 6-methylheptanoic acid. (KMn04 cleaves 1,2-diols to yield carboxylic acids.) Neglecting stereochemistry, propose a structure for disparlure. The actual compound is a chiral molecule with 7ft,8S stereochemistry. Draw disparlure, showing the correct stereochemistry.
