Abstract
Disparlure, the sexual feromone of the Gypsy Moth, has been prepared via the known intermediate 2-methyl-7-octadecyne, using a new constructional principle: C9 + C10 → C19. The so far undescribed 7-methyl-1-octyne was used as the C9 component. The advantages of this procedure consist in higher yields of disparlure and in a substantial simplification of the method of purification of 2-methyl-7-octadecyne.
