3-O-Ethyl-8-epi-9-epi-furandiol (2) has been synthesised from natural 3-O-ethyl-furandiol (Artifact) (1) isolated from extracts of Lactarius vellereus. The structure of 2 was investigated by X-ray diffraction. The compound 2 crystallises in an orthorhombic system, space group P212121, with cell constants a = 7.308(2), b = 14.629(4), and c = 14.702(3) A. The crystal structure was solved by direct methods and refined by a full-matrix, least-squares procedure to give R = 0.045 (Rw = 0.048, statistical weights). The expected trans-fused configuration of the 7- and 5-membered rings in 2 was fully confirmed. The conformations of fused rings are discussed.

Very high antifeedant activity of 3-O-ethylfurandiol (1,"artifact") against the storage pests Sitophilus granarius L. and Tribolium confusum Duv. prompted us to synthesize 8-epi-9-epi (trans fused) derivatives to examine their antifeedant activity.The structures of compounds were substantiated by spectroscopy.The results of antifeedant activity are presented.Key words: 3-Ethoxy-9-epi-lactarane (trans fused) sesquiterpenes, synthesis, antifeedant activity, storage pests, Tribolium confusum Duv., Trogoderma granarium, Sitophilus granarius
