The antifeedant activity towards larvae of Leptinotarsa decemlineata and Spodopttea littoralis and the hot taste for the human tongue have been determined for natural and synthetic 1,4-dialdehydes la, Ib, 2,3,6,7,8, and 9. Among the bicyclic dialdehydes the biological activity has been found to be dependent on the distance between the two aldehyde groups; tricyclic and pentacyclic dialdehydes are inactive in both tests. A short synthetic route to (- )- and ( + )-polygodial [1a, 1 b] is reported.

Abstract
The antifeedant activity towards larvae of Leptinotarsa decemlineata and Spodopttea littoralis and the hot taste for the human tongue have been determined for natural and synthetic 1,4-dialdehydes la, Ib, 2,3,6,7,8, and 9. Among the bicyclic dialdehydes the biological activity has been found to be dependent on the distance between the two aldehyde groups; tricyclic and pentacyclic dialdehydes are inactive in both tests. A short synthetic route to (- )- and ( + )-polygodial [1a, 1 b] is reported.File in questo prodotto:
