Monosubstituted Oxazoles. 1. Synthesis of 5-Substituted Oxazoles by Directed Alkylation

The Journal of Organic Chemistry, 1998
A general method is presented for synthesis of 2-(methylthio)-5-substituted oxazoles 2. Deprotonation of the readily available 2-(methylthio)oxazole (1) with n-BuLi occurs smoothly in the presence of TMEDA and regiospecifically at C5. The organometallic 1a added rapidly to aldehydes and other electrophiles to provide 5-substituted-2-(methylthio ...

Unconventional oxazole formation from isocyanides

Chemical Communications, 2009
The coupling of an acyl chloride with an isocyanide affords 2,5-disubstituted oxazoles under mild basic conditions instead of 4,5-disubstituted derivatives when using Schöllkopf conditions (butyllithium); this reaction constitutes a remarkable example of a base-induced chemoselective process in isocyanide chemistry.
