Translocative Rearrangements. Generality of the Formamidine-Induced Rearrangement of 4-Substituted 5-Amino-4-cyano-4H-imidazoles

Article abstract of DOI:10.1021/jo00149a002

The generality of two different courses of cyclisation reactions for 4-substituted 5-amino-4-cyano-4H-imidazoles (5) is demonstrated.One results from treatment of 5 with formamidine in a "translocative rearrangement" that leads to 8-substituted 4-aminoimi
