Diols as Dienophiles: Bridged Carbocycles via Ruthenium(0)‐Catalyzed Transfer Hydrogenative Cycloadditions of Cyclohexadiene or Norbornadiene |
|
| Abstract: | Highly exo‐selective ruthenium(0) catalyzed transfer hydrogenative cycloadditions of 1,2‐diols with cyclohexadiene or norbornadiene are described. Novel bridged bicyclic ring systems are accessible from the diol, α‐ketol or 1,2‐dione oxidation levels with complete control of diastereoselectivity. |
