The highly efficient asymmetric total syntheses of (-)-Δ(8)-tetrahydrocannabinol ((-)-Δ(8)-THC) (13 steps, 35%) and (-)-Δ(9)-tetrahydrocannabinol ((-)-Δ(9)-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 S(N)Ar cyclization.
通过使用钌催化的外消旋α-芳基环状酮的不对称氢化动力学拆分和分子内 S(N)Ar 环化,发展了高效不对称全合成(-)-Δ(8)-四氢大麻酚((-)-Δ(8)-THC)(13 步,35%)和(-)-Δ(9)-四氢大麻酚((-)-Δ(9)-THC)(14 步,30%)的方法。
