Direct Arylation of Oxazoles at C2. A Concise Approach to Consecutively Linked Oxazoles
Organic Letters, 2008The synthesis of bis- and trisoxazoles via direct arylation is discussed. A variety of aryl groups can be installed at the 2-position of 5-aryl and 5-carboxy-substituted oxazoles under mild conditions using palladium catalysis on water. The direct arylation method can be extended to the synthesis of bis- and trisoxazoles if 2-triisopropylsilyl-4 ...

Monosubstituted Oxazoles. 1. Synthesis of 5-Substituted Oxazoles by Directed Alkylation
The Journal of Organic Chemistry, 1998A 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 ...

Abstract Oxazole-4-sulfones, -phosphonates, and -nitriles are prepared by rhodium(II) catalysed addition of nitriles to the corresponding diazo compound. The effect of the ligand on rhodium was briefly investigated, with rhodium(II) trifluoroacetamide generally proving the most effective catalyst.
