Abstract
A process for making piperitone from crude plinols involving hydrogenating the crude plinols to form dihydroplinols and dehydrating the dihydroplinols to yield an iridene. The iridene is then oxidatively cleaved at the unsaturation to form an acyclic dione. The dione is cyclized in the presence of a base to form piperitone.
