##### Disparlure, $\mathrm{C}_{19} \mathrm{H}_{38} \mathrm{O},$ is a sex attractant released by the female gypsy moth, Lymantria dispar. The $^{1} \mathrm{H}$ NMR spectrum of disparlure shows a large absorption in the alkane region, 1 to $2 \delta,$ and a triplet at 2.8 $\delta .$ Treatment of disparlure, first with aqueous acid and then with $\mathrm{KMnO}_{4}$, yields two carboxylic acids identified as undecanoic acid and 6 -methylheptanoic acid. (KMnO$_4$cleaves 1,2-diols to yield carboxylic acids.
