An efficient microwave-assisted one-pot two-step protocol was developed for the construction of disubstituted 2-amino-1H-imidazoles. This process involves the sequential formation of 2,3-dihydro-2-hydroxyimidazo[1,2-a]pyrimidinium salts from readily available 2-aminopyrimidines and α-bromoketones, followed by cleavage of the pyrimidine ring with hydrazine.

The formation constants of some transition metal ions Cr(III), Mn(II), Fe(III), Ni(II) and Cu(II) binary complexes containing Schiff bases resulting from condensation of salicylaldehyde with aniline (I), 2-aminopyridine (II), 4-aminopyridine (III) and 2-aminopyrimidine (IV) were determined pH-metrically in ethanolic medium

The search for new and potent histamine H4 receptor ligands is leading to a steadily increasing number of scientific publications and patent applications. Several interesting and structurally diverse compounds have been found, but fierce IP competition for a preferred 2-aminopyrimidine
A series of new 2-(2-aminopyrimidin-4-yl)phenol derivatives were synthesized as potential antitumor compounds. Substitution with pyrrolidine-3,4-diol at the 4-position of phenol provided potent inhibitory activity against CDK1 and CDK2. X-ray crystal structural studies were performed to account for the effect of
A synthetic strategy to access small libraries of triazolylmethoxy chalcones 4{1-20}, triazolylmethoxy flavanones 5{1-10} and triazolylmethoxy aminopyrimidines 6{1-17} from a common substrate 4-propargyloxy-2-hydroxy acetophenone using a set of different reactions has been developed. The chalcones and flavanones were screened against
