Application

3-Bromo-2-butanone can be used as a reactant to synthesize:
  • N



  • -(4,5-Dimethyl-1H-imidazol-2-yl)acetamide by reacting with N-acetylguanidine under acidic conditions.[1]
  • Oxazole derivatives by silver triflate catalyzed cyclization reaction with various amides.[2]
  • 2-bromo-5,6-dimethyl[1,3]oxazolo[3,2-b][1,2,4]triazole by treating with 3,5-dibromo-1,2,4-triazole in the presence DBU.[3]

A microwave-assisted protocol was developed for the construction of di- and monosubstituted 2-aminoimidazoles. The two-step reaction involves the synthesis of N-(1H-imidazol-2-yl)acetamides from readily available alpha-haloketones and N-acetylguanidine, followed by deacetylation. Significant rate enhancement was observed for both steps of the
