Abstract

Hydrogenation of some natural neo-clerodanes on 10% Pd/C resulted in the saturation of the furan ring and in some cases hydrogenolysis of the epoxide system and or γ-lactone ring. Overall, reduction of the furan ring found in the natural compounds resulted in a decrease in the antifeedant activity of the compounds against the lepidopteran pests, Heliocoverpa armigera and Spodoptera frugiperda. However, two of the most active derivatives had both the furan ring and the lactone ring hydrogenated but the epoxide intact.
