[1,2]-Wittig Rearrangement of Aromatic Heterocycles
摘要:
Anionic rearrangement of diverse heteroaryl ethers is reported. In many cases, directed metallation followed by formal [1,2]-Wittig rearrangement provides heteroaryl carbinols in good yield.

A new LiI-promoted O- to N-alkyl migration has been developed for the conversion of O-alkylated 2-hydroxy pyridines, quinolines, and pyrimidines to the corresponding N-alkylated heterocycles in good to excellent yields (57−99%). This method serves as an efficient means for the preparation of N-benzyl pyridones, quinolones, and pyrimidones.

The present study reports the synthesis of N‐alkylated pyridones and benzothiazolones via O‐ to N‐alkyl group migration under transition metal‐free TfOH‐catalyzed reaction conditions for the first time, to the best of our knowledge. Primary as well as secondary alkyl groups smoothly migrate under the present reaction conditions. Moreover, a minor modification of the protocol used in this study is found
