Reactions of Nitroimidazodihydrooxazole with Alcohols and Phenols in the Presence of Potassium Carbonate

Żwawiak J., Gzella A., Zaprutko L.

Polish Journal of Chemistry

2009

Vol. 83, nr 7

Dihydrooxazole ring opening reactions in bicyclic nitroimidazodihydrooxazoles with simultaneous Williamson ethe real groups formation are described. It was found that only mutual action of K2CO3, phenol and alcohol can cause such reaction. Its mechanism consists of three steps. In a result, a series of 3-phenoxy-1-(5-alkoxy-4-ni tro- 1H-imidazol-1-yl)propan-2-ols has been obtained. The structure of new compounds was confirmed by single crystal X-ray analysis.
