چکیده
The title compound, C(20)H(19)N(3)O(3)·C(3)H(7)NO, was synthesized by the reaction of 6-amino-pyrimidine-2,4(1H,3H)-dione and 4-methyl-benzaldehyde with 5,5-dimethyl-1,3-cyclo-hexa-nedione in 1-butyl-3-methyl-imidazolium bromide at 363 K. The pyrimidine ring adopts a half-chair conformation while the six-membered ring fused to the pyridine ring adopts a skew-boat conformation. The dihedral angle between the pyridine ring and the attached benzene ring is 2.38(8)°

متن کامل(E)-3-Methyl-4-[(2-oxidoquinolin-1-ium-3-yl)methyleneamino]-1H-1,2,4-triazole-5(4H)-thione N,N-dimethylformamide solvate
The title 1,2,4-triazole compound, C(13)H(11)N(5)OS·C(3)H(7)NO, crystallizes as a 1:1 dimethyl-formamide (DMF) solvate. The main mol-ecule exists in a trans configuration with respect to the acyclic C=N bond. An intra-molecular C-H⋯S hydrogen bond generates an S(6) ring motif. In the synthesis, a proton is transferred from the O atom of a hydr-oxy group to the quinoline group N atom. The essent...

We report here the structure of the title compound, (I) (Fig. 1), which was prepared by microwave irradiation of a twocomponent mixture of a 6-aminopyrimidine and the condensation product formed from dimedone and formaldehyde. By contrast a similar reaction between 6-aminopyrimidines, 5,5dimethylcyclohexane-1,3-dione and a large excess of formaldehyde yielded spiranopyridopyrimidines (Quiroga e...
