(4Z,6Z)-4,6-Bis(4-methoxybenzylidene)-2,2-dimethyl-1,3-dioxan-5-one
The title compound, C(22)H(22)O(5), crystallizes with two independent mol-ecules in the asymmetric unit, both of which possess pseudo-C(s) symmetry. The central 1,3-dioxanone rings have envelope conformations, with the C atom bearing the two methyl groups at the flap. The benzene rings of the meth-oxy-benzyl-idene units, attached in the 4- and 6-positions on the central 1,3-dioxanone rings, are...

The title compound, C(15)H(14)N(2)O(4), is approximately planar, with a dihedral angle of 6.48 (4)° between the amino-methyl-ene unit and the planar five-atom part of the dioxane ring, and a dihedral angle of 2.40 (4)° between amino-methyl-ene unit and the phenyl-ene ring. The dioxane ring is envelope shaped, with the dimethyl-substituted C atom that represents the flap 0.535 (8) Å out of the p...

In the title compound, C(13)H(11)N(3)O(4), the dioxane ring adopts an envelope conformation with the C atom bonded to the dimethyl group in the flap position [deviation = 0.613 (1) Å]. The nitrile group and the attached benzene ring are roughly coplanar [maximum deviation = 0.087 (1) Å]. An intra-molecular N-H⋯O hydrogen bond involving the hydrazinyl group generates an S(6) ring. The N-N and C-...

In the title compound, C12H16FNO3, the dioxane ring adopts a chair conformation with the methyl groups and amine N atom in equatorial positions. The best plane through the dioxane ring makes a dihedral angle of 43.16 (8)° with the phenyl ring. In the crystal, pairs of C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R 2 (2)(8) dimers, which are linked into [100] chains by further C...
متن کاملN-(4-Fluorophenyl)-2,6-dimethyl-1,3-dioxan-4-amine
In the title compound, C12H16FNO2, the dioxane ring adopts a chair conformation with the methyl substituents and the C-N bond in equatorial orientations. Its mean plane subtends a dihedral angle of 40.17 (6)° with the benzene ring. In the crystal, weak N-H⋯F hydrogen bonds link the mol-ecules into C(7) chains propagating in [100].
