In the title compound, C(19)H(22)N(4)O(2), the tetra-hydro-pyrimidine ring adopts an envelope conformation (with the N atom connected to the benzyl group representing the flap). This benzyl group occupies a quasi-axial position. The two benzyl groups lie over the tetra-hydro-pyridimidine ring. The amino group is a hydrogen-bond donor to the nitro group.

The synthesis and investigation of new Hetero Cyclic Dithicarbamate ligand and its solid metal complexes derived from 4-Amino-1,2,4triazole(ATAZ) and 2-Amino 4-Hydroxy-6-methyl pyrimidine (AHPY) by using different synthetic methods. The derived colored complexes are Au (III) and Ru (III) with above mentioned ligands. The structures and bio cancer activity were elucidated by different type of st...

Salicylidene acylhydrazides are inhibitors of type III secretion in several gram-negative pathogens. To further develop the salicylidene acylhydrazides, scaffold hopping was applied to replace the core fragment of the compounds. The novel 2-(2-amino-pyrimidine)-2,2-difluoroethanol scaffold was identified as a possible analog to the salicylidene acylhydrazide core structure. The synthesis of a l...

Colourless crystals of the title mixed ligand complex, [Ag(C(5)H(7)N(3))(C(6)H(9)N(3))]ClO(4), were obtained from a solution of 2-amino-4-methyl-pyrimidine, 2-amino-4,6-dimethyl-pyrim-idine and silver perchlorate in water and methanol. The crystal structure is stabilized by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds and π-π stacking inter-actions of the aromatic rings of the two ligands [in...

The title compound, C33H35N3O5, is the product of the multicomponent condensation of 1-benzyl-4-eth-oxy-carbonyl-piperidin-3-one with 1,5-bis-(2-formyl-phen-oxy)-3-oxapentane and ammonium acetate. The mol-ecule comprises a penta-cyclic system containing the aza-14-crown-4-ether macrocycle, tetra-hydro-pyrimidine, tetra-hydro-pyridine and two benzene rings. The aza-14-crown-4-ether ring adopts a...

The title compound, C(12)H(19)BrN(4)O, represents the minor component of the two products obtained in a series of transformations involving the Grignard reaction of tert-butoxy-carbonyl-protected 4-amino-cyclo-hexa-none with MeMgBr, and subsequent inter-action of the obtained amino-substituted cyclo-hexa-nol with 4-chloro-6-methyl-pyrimidin-2-amine followed by bromination with N-bromo-succinimi...

The crystal structure of the title compound, C5H4N2O2, is built of acid mol-ecules located on a mirror plane. They form sheets stacked along the b-axis direction. The mol-ecules inter-act via O-H⋯N hydrogen bonds, forming [001] chains, and weak van der Waals inter-actions.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(13)H(13)N(5). In each mol-ecule, an amino N atom is connected to a benzimidazole fused-ring system and a pyrimidine ring [these are aligned at 1.3 (1)° in one independent mol-ecule and at 5.4 (1)° in the other]. The amino N atom of the fused ring forms an intra-molecular N-H⋯O hydrogen bond to a pyrimidine N at...

We investigated an uncommon biotransformation of pyrimidine during the metabolism of GNE-892 ((R)-2-amino-1,3',3'-trimethyl-7'-(pyrimidin-5-yl)-3',4'-dihydro-2'H-spiro[imidazole-4,1'-naphthalen]-5(1H)-one), a β-secretase 1 inhibitor. Three novel metabolites, formed by conversion of pyrimidine to pyrazole, were observed in the (14)C-radiolabeled mass balance study in rats. Their structures were ...
