  作者：Philippe Gros、Yves Fort、Philippe Pierrat

  DOI：10.1055/s-2004-831337

  日期：——

  The reaction of lithiating agents with various 3-bromopyridines has been investigated. An unprecedented selectivity was observed with t-BuLi, which effected a clean lithiation at C-4. With 3-bromo and 2-chloro-3-bromo pyridines, the ortholithiation-exchange ratio was strongly electrophile and addition order dependent while 2-chloro-5-bromopyridine always gave exclusive C-4 substitution.

  对各种3-溴吡啶与锂化试剂的反应进行了研究。使用t-BuLi时观察到了前所未有的选择性，在C-4位置实现了干净的锂化。对于3-溴和2-氯-3-溴吡啶，邻位锂化的交换比在很大程度上依赖于电亲和性和加成顺序，而2-氯-5-溴吡啶则始终只产生C-4取代反应。

• Lithiation of 2-Chloro- and 2-Methoxypyridine with Lithium Dialkylamides: Initial Ortho-Direction or Subsequent Lithium Ortho-Stabilization?
  作者：Philippe Gros、Sabine Choppin、Yves Fort

  DOI：10.1021/jo026559u

  日期：2003.3.1

  The lithiation pathway of 2-chloro and 2-methoxypyridine with LDA and LTMP has been investigated using deuterated probes. The availability of both H-6 and H-3 protons on the pyridine nucleus was found to be critical to ensure complete C-3 lithiation. We thus concluded that the C-3 lithiation was not a straightforward process. A mechanism involving precomplexation of lithium dialkylamides near the H-6 proton and formation of a 3,6-dilithio pyridine intermediate is proposed.
