Synthesis and characterization of 3-methyl-6-[(propynyloxy)methyl]-1,4-dioxane-2,5-dione
The number of known asymmetrically substituted hemilactides, important precursors for obtaining regular derivatives of polylactide polymers, is still limited and structural characterization of most of them is incomplete. In the title racemic 1,4-dioxane-2,5-dione derivative, C9H10O5, the hemilactide heterocycle exhibits a twist-boat conformation. The bulkier propynyloxymethyl group is in an axi...
متن کامل2,2-Dimethyl-5-[(3-nitroanilino)methylene]-1,3-dioxane-4,6-dione
The benzene ring of the title compound, C(13)H(12)N(2)O(6), is twisted away from the planes of the amino-methyl-ene unit and the dioxane ring by 30.13 (4) and 35.89 (4)°, respectively. The dioxane ring exhibits a half-boat conformation, in which the C atom between the dioxane O atoms is 0.553 (8) Å out-of-plane. An intra-molecular N-H⋯O hydrogen bond stabilizes the conformation of the dioxane r...
متن کامل(E)-2,2-Dimethyl-5-(3-phenylallylidene)-1,3-dioxane-4,6-dione
The title compound, C(15)H(14)O(4), was prepared by the reaction of 2,2-dimethyl-1,3-dioxane-4,6-dione and (Z)-3-phenyl-acryl-aldehyde in ethanol. The dioxane ring is in a sofa conformation with the C atom bonded to the two methyl groups forming the flap. With the exception of the flap atom and the methyl group C atoms, all other non-H atoms are essentially planar, with an r.m.s. deviation of 0...
متن کامل6-[3-(2,4-Dimethylanilino)-2-hydroxypropoxy]-1,8-dihydroxy-3-methyl-9,10-dihydroanthracene-9,10-dione
In the title compound, C(26)H(25)NO(6), the anthraquinone ring system forms a dihedral angle of 15.5 (1)° with the benzene ring of the dimethyl-aniline group. Intra-molecular O-H⋯O hydrogen bonding is observed between the carbonyl and two hydroxyl groups. The mol-ecules are linked into a ribbon-like structure along the [100] direction by O-H⋯N and C-H⋯O hydrogen bonds. The crystal used was twin...
متن کامل6-Chloro-8-methyl-4H-3,1-benzoxazine-2,4(1H)-dione
The two mol-ecules in the asymmetric unit of the title compound, C(9)H(6)ClNO(3), are nearly planar, with r.m.s. deviations of 0.034 and 0.037 Å. The crystal structure is stabilized by two weak inter-molecular N-H⋯O inter-actions.
