Abstract
An inexpensive, stereoselective synthesis for nootkatone, tetrahydronootkatone, and their derivatives is disclosed utilizing ozonolysis. The starting materials used in the synthesis are inexpensive and the reactions are commercially feasible and amenable to scaling up. The principal starting material, (−)-β-Pinene, is on the GRAS list (generally recognized as safe).
