- (-)-Cameroonanol has been isolated from the essential oil of Echinops giganteus (globe thistle) plants and it is associated with a strong woody fragrance. Its structure, includ- ing relative stereochemistry, was confirmed when it was made in the laboratory according to the sequence shown below.' Recall that a C=C bond is made up of one o bond and one 7 bond. These two bonds together have a combined BDE (bond dissociation energy) of 607 kJ/mol.
