In ethyl 5-cyano-2,6-dimethyl-4-(5-nitro-2-furyl)-1,4-dihydropyridine-3-carboxylate, C15H15N3O5, the molecules are linked into chains by a single N-H...O hydrogen bond. The molecules in diethyl 2,6-dimethyl-4-(5-nitro-2-furyl)-1,4-dihydropyridine-3,5-dicarboxylate, C17H20N2O7, are linked by a combination of one N-H...O hydrogen bond and two C-H...O hydrogen bonds into sheets built from equal nu...

ABSTRACT
 
 Isolation of essential oil by steam and water distillation method, identification GC-MS antibacterial activity test against akway bark (D. arfakensis Gibbs) have been carried out. The results showed that the component was composed 142 compounds, which were dominated 10 components. ten suspected components are: 4,5-dimethyl-1-heksen (4,15%); 4-methyl-1-ol-3-penten (3,93%); ...

In the title compound, C(11)H(18)N(4)O(2) (systematic name: 2-dimethyl-amino-5,6-dimethyl-pyrimidin-4-yl N,N-dimethyl-carb-amate), the pyrimidine ring and dimethyl-amino group are almost in the same plane, making a dihedral angle of 1.6 (1)°. The dihedral angle between the mean plane of the pyrimidine ring and that of the dimethyl-carbamate group is 83.42 (5)°. In the crystal structure, inter-m...

Studies in Cucinogenesis. V. Methyl Derivatives of 1 : 2-Benzanthracene, M. J. SHEAR. In a further contribution to his series of studies on carcinogenesis Shear records his experiments with the methyl derivatives of 1 : 2-benzanthracene and related compounds. Of 21 compounds examined 10 produced tumors in mice a t the injection site. The more potent carcinogenic compounds were 5 : 10-dimethyl-1...

The compound 2-((1,3-dimethyl-1H-pyrazol-5-yl)(methyl)carbamoyl)benzene-diazonium hydrogen sulfate (10) was reacted with copper sulfate and sodium chloride, in the presence of ascorbic acid as reducing agent, to afford a mixture of the chlorinated epimers 4'-chloro-2,2',5'-trimethyl-2',4'-dihydrospiro[isoindoline-1,3'-pyrazol]-3-one (18) and (19), the epimers 4'-hydroxy-2,2',5'-trimethyl-2',4'-...
