A convenient synthesis of oxazolines and imidazolines from aromatic aldehydes with pyridinium hydrobromide perbromide in water
Various 2-oxazolines were prepared from aromatic aldehydes and 2-aminoethanol with pyridinium hydrobromide perbromide in water at room temperature. 2-Imidazolines were also obtained in good yields from aromatic aldehydes and ethylenediamine under the same reaction conditions.
