Converting oxazoles into imidazoles: New opportunities for diversity-oriented synthesis

Alzieu, Thibaut,Lehmann, Johannes,Naidu, Ajay B.,Martin, Rainer E.,Britton, Robert

supporting information, p. 1867 - 1870 (2014/02/14)

We report the optimization of a neglected reaction for the rapid and direct conversion of oxazoles into N-substituted imidazoles. The utility of this microwave-promoted reaction for diversity-oriented synthesis is demonstrated in the preparation of >40 N-substituted imidazoles, including α-imidazolyl esters.
