Palladium(0)-Catalyzed Arylative Dearomatization of Phenols
摘要:
The palladium-catalyzed arylative dearomatization of phenols to yield spirocyclohexadienone products in good to excellent yields has been developed. Preliminary results demonstrate that the formation of the spirocyclic all-carbon quaternary center can be accomplished with high levels of enantiocontrol (up to 91% ee).

cationic alkynyl Heck reaction between aryl triflates and alkynes to give substituted allenes is described. Key to the success of this method was the discovery and development of a new hybrid Pd(0)-catalyst, BobCat, that incorporates a water-soluble dba-ligand and biaryl phosphine ligand to provide substituted allenes in good yields under mild reaction conditions.
