Very high antifeedant activity of 3-O-ethylfurandiol (1, ''artifact'')
[1] against the storage pests Silophilus granarius L, and Tribolium c
onfusum Duv. prompted us to synthesize 8-epi-9-epi (Im,ls fused) deriv
atives to examine their antifeedant activity. The structures of compou
nds were substantiated by spectroscopy. The results of antifeedant act
ivity are presented.
