摘要

本文首次报道了一种未受保护的 2-烷基吡啶的对映选择性还原方法。以频哪醇硼烷和酰胺为还原剂，通过 1,4-氢化和随后的转移氢化级联过程，合成了大量 2-烷基哌啶类化合物，产量高，对映选择性好。得到的产物可以很容易地转化为天然生物碱。

Borane-Catalyzed Asymmetric Reduction of 2-Alkylpyridines†

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 converted to natural alkaloids.
