متن کاملCrystal structure of 4-(4-methoxyphenyl)-7,7-dimethyl-2-methylamino-3-nitro-7,8-dihydro-4H-chromen-5(6H)-one
In the title compound, C19H22N2O5, the six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation with the dimethyl-substituted C atom as the flap. The pyran ring has a flat-boat conformation. The meth-oxy-phenyl ring is orthogonal to the mean plane of the chromene moiety, with a dihedral angle of 89.97 (8)°. The amine N atom deviates from the chromene mean plane by 0....
متن کاملCrystal structure of 15,16-epoxy-7β,9α-dihydroxylabdane-13(16),14-dien-6-one
In the title mol-ecule, C20H30O4, both cyclo-hexane rings adopt chair conformations. In the crystal, mol-ecules are connected by O-H⋯O hydrogen bonds forming chains along [100]. In addtion, an intra-molecular O-H⋯O hydrogen bond forms an S(5) ring.

The hetero-tetra-cene skeleton of the title mol-ecule, C23H14Br2N2OS, is defined by linear annulation of four six-membered rings, including two N heteroatoms. This moiety is nearly planar (r.m.s. deviation = 0.055 Å), with a slight twist of 4.1 (2)° between the two halves of the aromatic system. The dihedral angle between the least-squares plane of the skeleton and the benzyl group is 24.5 (3)°...
