The highly efficient asymmetric total syntheses of (−)-Δ8-tetrahydrocannabinol ((−)-Δ8-THC) (13 steps, 35%) and (−)-Δ9-tetrahydrocannabinol ((−)-Δ9-THC) (14 steps, 30%) have been developed by using ruthenium-catalyzed asymmetric hydrogenation of racemic α-aryl cyclic ketones via dynamic kinetic resolution and intramolecular SNAr cyclization.
