benzo‐fused quinolizidines, indolizidines, and their analogues by ruthenium‐catalyzed asymmetric cascade hydrogenation/reductive amination of quinolinyl‐ and quinoxalinyl‐containing ketones has been developed. This reaction proceeds under mild reaction conditions, affording chiral benzo‐fused aliphatic N‐heterocyclic compounds with structural diversity in good yields (up to 95 %) with excellent diastereoselectivity
已开发了通过钌催化的含喹啉基和喹喔啉基酮的不对称级联氢化/还原胺化反应快速构建对映体富集的苯并稠合的喹喔啉,吲哚并iz及其类似物。该反应在温和的反应条件下进行,得到具有良好结构多样性的手性苯并稠合脂肪族N杂环化合物(高达95%),非对映选择性(高达> 20:1 dr)和对映选择性(高达> 99%)ee)。此外,该催化方案适用于(+)-gephyrotoxin的正式合成。
