Pyralid moths

Scheme 14 illustrates Linstrumelle s synthesis of (9Z,11 )-9,11,13-tetradeca-trienyl acetate (8), the pheromone of the pyralid moth, Stenoma cecropia [25]. The key steps were palladium and copper-catalyzed Sonogashira couplings (A+B and C+D). Another noteworthy feature in this synthesis was the use of activated zinc dust in aqueous methanol for the reduction of the triple bonds of E to give two double bonds of 8.

Only few insects have adapted to quitiolizi-dine alkaloids and sequester them as defense compounds, e.g., some aphids and larvae of the pyralid moth Uresiphita reversalis (Wink and Witte, 1991 Montllor et al., 1990). This is in contrast to pyrrolizidines, which are utilized by a large number of butterflies and beetles.
