1-Aza-1',3'-diaza-3,3'-sigmatropic rearrangements - A convenient synthesis of benzimidazole derivatives
1-Aryl-2-acyl-2-cyanohydrazines undergo smooth thermal rearrangements to provide 2-aminoacylbenzimidazoles in excellent yields. A short synthesis of the highly mutagenic dietary amine, IQ, is reported.
