Crystal structure of 1-isopropyl-4,7-dimethyl-3-nitronaphthalene
The title compound, C15H17NO2, was synthesized from a mixture of α-himachalene (2-methyl-ene-6,6,9-tri-methylbi-cyclo-[5.4.0(1,7)]undec-8-ene) and β-himachalene (2,6,6,9-tetra-methylbi-cyclo-[5.4.0(1,7)]undeca-1,8-diene), which were isolated from an oil of the Atlas cedar (Cedrus Atlantica). The naphthalene ring system makes dihedral angles of 68.6 (2) and 44.3 (2)°, respectively, with its atta...
متن کامل2,3-Dimethyl-6-nitro-2H-indazole
In the mol-ecule of the title compound, C(9)H(9)N(3)O(2), the indazole ring system is almost planar [maximum deviation = 0.019 (3) Å for the C atom bearing the nitro group]. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into centrosymmetric dimers, forming R(2) (2)(18) ring motifs. Aromatic π-π contacts between indazole rings [centroid-centroid distances = 3....

In the title compound, C17H28N2O3, the isoxazolidine ring adopts an envelope conformation with the O atom deviating from the mean plane of the other four ring atoms by 0.617 (1) Å. In the crystal, mol-ecules are linked via weak C-H⋯O hydrogen bonds, forming chains which extend along the b-axis direction.
متن کامل1-Isopropyl-4-nitro-6-methoxy-1H-benzimidazole
There are two independent mol-ecules in the asymmetric unit of the title compound, C(11)H(13)N(3)O(3). The inter-planar angles for the two rings of the benzimidazole ring system is 2.21 (12)° in one mol-ecule and 0.72 (12)° in the other. The nitro group is twisted in the same direction relative to the least-squares plane through its attached benzene ring in both mol-ecules, with inter-planar an...

Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
