Crystal structure of 5-[4-(diethylamino)benzylidene]-2,2-dimethyl-1,3-dioxane-4,6-dione
The title compound, C17H21NO4, consists of substituted Meldrum's acid with a [4-(di-ethyl-amino)-phen-yl]methyl-idene fragment attached to the fifth position. The heterocycle assumes a distorted boat conformation. The planar part of heterocycle is almost coplanar with the benzene ring due to the presence of a long conjugated system in the mol-ecule. This leads to the formation of C-H⋯O-type int...
متن کامل5-(4-Hydroxybenzylidene)-2,2-dimethyl-1,3-dioxane-4,6-dione
The title compound, C(13)H(12)O(5), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and 4-hy-droxy-benz-alde-hyde in ethanol. The 1,3-dioxane ring is in a distorted boat conformation. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(20) rings.

The title compound, C(13)H(12)ClNO(4), is approximately planar, with a dihedral angle of 8.23 (4)° between the mean plane of the amino-methyl-ene unit and the planar part of the dioxane ring. The dioxane ring has a half-boat conformation, in which the C atom between the dioxane O atoms is -0.464 (8) Å out of the plane of the other five atoms. In the mol-ecule there is an intra-molecular N-H⋯O h...

In the title compound, C(13)H(12)BrNO(4), the dihedral angles between the amino-methyl-ene group and the dioxane ring and between the benzyl ring and the amino-methyl-ene unit are 7.96 (4) and 12.15 (4)°, respectively. The dioxane ring shows a half-boat conformation, in which the C atom between the dioxane ring O atoms is 0.460 (8) Å out of the plane through the remaining ring atoms. An intra-m...
