9-Bromo-11-oxo-hexahydrocannabinol (5) was prepared from the ketocannabinoid 3b via the epoxysulfone 4. The dehydrobromination of the bromoaldehyde 5 could be controlled to give either the thermodynamically more stable Δ8-aldehyde 2c, or the Δ9-aldehyde 1c by an intramolecularly assisted elimination. Reduction of the unsaturated aldehydes gave the allylic alcohol metabolites 2a and 1a, respectively.
