Herein, a method for the enantioselective reduction of unprotected 2-alkylpyridines is reported for the first time. By using pinacolborane and an amide as reducing agents, a large number of 2-alkylpiperidines were synthesized with high yields and excellent enantioselectivities via a cascade process involving 1,4-hydroboration and subsequent transfer hydrogenation. The resulting products can be easily
在此,首次报道了一种对映选择性还原未受保护的 2-烷基吡啶的方法。通过使用频联硼烷和酰胺作为还原剂,通过涉及 1,4-硼氢化和随后转移氢化的级联过程合成了大量 2-烷基哌啶,产量高且对映选择性优异。所得产品可以很容易地转化为天然生物碱。
