[Cp*Ru]-catalyzed selective coupling/hydrogenation

摘要

Access to 3,4-and 3,5-disubstituted piperidine derivatives has been achieved through [Cp*Ru]-catalyzed intermolecular coupling of allylic alcohols and propargylic amides. Tandem transformation was also possible via chemoselective [Cp*Ru]-catalyzed hydrogenation of the resulting homodienes.
