Abstract

Specionin (1) was synthesized in seven steps from aucubin (2), an abundant iridoid form aucuba japonica. In a "no-choice" bioassay, specionin and several of its derivatives showed only modest antifeedant activity against the spruce budworm, while other derivatives were devoid of activity.
