Spectroscopic examination of some historical samples from the terpene collection of Prof. H. Wienhaus resulted in the structure elucidation of dieucarvelones A, B and C, products of treatment of eucarvone with zinc in alkali and in confirmation of the structure of α-amyrilene, a rearrangement product of α-amyrin. The relative stereochemistry of dieucarvelones A and C was established by X-ray crystallographic analyses.
