The present disclosure is directed to a process for the chemical synthesis of (-)-Δ9- ^tetrahydrocannabinol (Δ9-THC) and related compounds of formula (I). In particular, the process comprises a one-pot condensation and sulfonylatton reaction sequence that produces crude Δ9-THC aryl sulfonate or related compounds. Sulfoπylatioπ of Δ9-THC or related compounds immediately upon their formation imparts stability to the cannabinoids, and prevents formation of the corresponding Δ8 isomer. Δ9THC aryl sulfonates may be readily separated from A6THC aryl sulfonates using reverse phase chromatography. Hydrolysis of the Δ9-THC aryl sulfonates or related compounds produces Δ9-THC or related compounds containing relatively low amounts of the corresponding Δ8 isomer. (Formula I).
