Abstract
With the use of ammonia borane as a hydrogen source, a borane catalyzed metal-free transfer hydrogenation of pyridines was successfully realized for the first time to furnish a variety of piperidines in 44-88% yields with moderate to excellent cis-selectivities. The ease in handling without requiring high pressure H2 makes this transfer hydrogenation practical and useful.
