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.
