    Lithiation of 2-Chloro- and 2-Methoxypyridine with Lithium Dialkylamides: Initial Ortho-Direction or Subsequent Lithium Ortho-Stabilization?
    摘要:
    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.

  • Aggregative activation in heterocyclic chemistry. Part 4. Metallation of 2-methoxypyridine: unusual behaviour of the new unimetal superbase BuLi–Me2N(CH2)2OLi (BuLi–LiDMAE)

    A series of potential unimetal superbases BuLi–ROLi has been studied in order to increase the basicity/nucleophilicity ratio ([B/N]R) of BuLi. The best [B/N]R ratio is found with BuLi–LiDMAE. This complex base apparently metallates 2-methoxypyridine at the unexpected C-6 position. It is shown that no actual metallated species are formed in the reaction medium, the reaction occurring as the result of a common radical precursor stabilized by an aggregate cluster. Finally, as an application, C-6 substituted 2-methoxypyridines have been obtained in good to excellent yields.
    为了提高BuLi的基本性/亲核性比率([B/N]R),研究了一系列潜在的单金属超碱BuLi–ROLi。最佳的[B/N]R比率是在BuLi–LiDMAE中发现的。这种复合碱显然在意想不到的C-6位点对2-甲氧基吡啶进行了金属化。研究表明,在反应介质中并没有形成实际的金属化物种,该反应是由于一个通过聚集簇稳定的共同自由基前体的结果。最后,作为应用,得到了C-6取代的2-甲氧基吡啶,产率良好到优异。
