An unprecedented, economical one-pot access to enantiopure N−H tetrahydropyridines is achieved by coupling a few readily available substrates with commercially available 1,3-amino alcohols via catalyticborrowinghydrogen. Highly diastereoselective functionalizations of tetrahydropyridines also result in a general access to enantiopure di- and tri-substituted piperidines, which rank among the most
