Facile Access to Novel 3-Acylimidazo[1,2-a]pyrimidines under Microwave Irradiation
摘要:
Treatment of mono-, bis- and tris(co-bromoacetophenone) derivatives with N,N-dimethylformamidine derivative of 2-aminopyrimidine, afforded the novel 3-aroyl or heteroyl derivatives of imidazo[1,2-a]pyrimidine, bis(imidazo[1,2-c]pyrimidine) and tris(imidazo[1,2-a]pyrimidine) derivatives, respectively, under both conventional and microwave conditions.
