Bamberger Fission and Reclosure of 1-Alkyl-5-(alkylamino)imidazole-4-carbonitriles Leading to Their 2-Oxo Derivatives

1-Methyl-5-(methylamino)imidazole-4-carbonitrile (4a) afforded three minor ring-opened products (5a, 6a, 10a) besides its 2-oxo derivative 3a on treatment with ethyl chloroformate in aqueous sodium bicarbonate. The geometrical isomers of these trisubstituted propenenitriles (5a, 6a, 10a) can be sepa...
