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 catalytic borrowing hydrogen. Highly diastereoselective functionalizations of tetrahydropyridines also result in a general access to enantiopure di- and tri-substituted piperidines, which rank among the most
通过催化借氢将一些现成的底物与市售的 1,3-氨基醇偶联,实现了前所未有的、经济的一锅法获得对映体纯 N−H 四氢吡啶。四氢吡啶的高度非对映选择性功能化也导致普遍获得对映体纯的二取代和三取代哌啶,它们是商业药物中最常见的 N- 杂环化合物。
