(-)-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, including relative stereochemistry, was confirmed when it was made in the laboratory according to the sequence shown below (Org. Lett. 2000, 2.2717-2719). Recall that a C-C bond is made up of one sigma bond and one pi bond. These two bonds together have a combined BDE (bond dissociation energy) of 607 kJ/mol. Use this information, together with the data in ) Table 6.1. to estimate the AH for the conversion of compound 1 into compound 2. H H OH pe H.
