    名称:
    Lithiation of 2-Heterosubstituted Pyridines with BuLi−LiDMAE:  Evidence for Regiospecificity at C-6
    摘要:
    The determination of the initial deprotonation site of 2-chloro- and 2-methoxypyridine during reaction with BuLi-LiDMAE has been investigated. A series of experiments on deuterated regioisomers revealed a direct lithiation at C-6 excluding a potential first classical ortholithiation and lithium equilibration in the reaction medium. These results suggested that the formation of lithium aggregates at the neighboring of the pyridinic nitrogen atom favored BuLi delivery at C-6 as well as 6-lithio intermediate stabilization.

  • 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.
