  A Divergent Synthesis of Substituted 2-Aminoimidazoles from 2-Aminopyrimidines

  摘要：

  A new divergent and efficient synthesis of substituted 2-aminoimidazoles 5 and 6 has been developed starting from the readily available 2-aminopyrimidines 1 and alpha-broinocarbonyl compounds 2, Using conventional heating or microwave irradiation. Thus, the cleavage of 1,2,3-substituted imidazo[1,2-a]pyrimidin-1 -iumsalts 4 with hydrazine or secondary amines led to 1,4,5-trisubstituted 2-aminoimidazoles 5, when the hydrazinolysis of 2-hydroxy-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-4-ium salts 3, followed by a novel Dimroth-type rearrangement, resulted in formation of 2-amino-1H-imidazoles 6. The relevant pathway of transformations was identified by characterization of the intermediates.

  general prevented the biofilm formation of both species at low micromolar concentrations, while salts with a shorter n-alkyl or cyclo-alkyl chain (C1–C5) or longer n-alkyl chain (C11–C14) were much less potent. Salts with a long cyclo-alkyl chain however were found to be strong biofilm inhibitors. Furthermore, we demonstrated the biofilm inhibitory potential of salts with certain aromatic substituents
