6,8-Dibromo-5-hydr-oxy-4-oxo-2-phenyl-4H-chromen-7-yl acetate.

ABSTRACT: In the title compound, C(17)H(10)Br(2)O(5), the chromene ring is almost planar with minimal puckering [total puckering amplitude = 0.067?(4)?Å]. The dihedral angle between chromeme ring system and phenyl ring is 3.7?(2)°. The crystal structure is stabilized by intermolecular C-H?O inter-actions and an intramolecular O-H?O hydrogen bond also occurs.

8-Hydr-oxy-5,6,7-trimeth-oxy-2-phenyl-4H-chromen-4-one.

Project description:In the title compound, C(18)H(16)O(6), the benzopyran group is essentially planar, with the O atoms of the substituent groups lying close to its mean plane. The mol-ecular conformation is governed by intra-molecular inter-actions. The crystal packing is mainly determined by one classical inter-molecular hydrogen bond which gives rise to the formation of an infinite chain along the a axis.

2-(5,7-Dimeth-oxy-4-oxo-4H-chromen-2-yl)phenyl 4-toluene-sulfonate.

Project description:In the crystal structure of the title compound, C(24)H(20)O(7)S, the chromone system makes a dihedral angle of 37.32 (7)° with the adjacent benzene ring. The chromone ring system and the tolyl ring are almost parallel, with a dihedral angle of 4.56 (9)°. The tolyl ring is twisted at an angle of 41.75 (6)° with respect to the benzene ring. Weak intra- and inter-molecular C-H⋯O inter-actions are observed.

4-(7-Acet-oxy-6-meth-oxy-4-methyl-2-oxo-2H-chromen-3-yl)phenyl acetate.

Project description:The title compound, C(21)H(18)O(7), is an important inter-mediate in the synthesis of 3-(4-hydroxy-phen-yl)-4-methyl-6-meth-oxy-7-hydroxy-coumarin, which is a nonsteroidal analogue of 2-methoxy-estradiol (2-ME). The substituent benzene ring is not in the same plane as the coumarin ring system, with a dihedral angle of 66.88 (10)°. There are some weak inter-molecular C-H⋯O inter-actions. One carbonyl O atom is disordered over two sites, with occupancies of 0.6 and 0.4.

Ethyl 2-[2-(4-oxo-4H-chromen-2-yl)phenoxy]acetate.

Project description:In the title flavonoid derivative, C19H16O5, the chromene portion is planar (r.m.s. deviation = 0.022 Å) with the substituents lying closely to the same plane. The dihedral angle between its mean plane and that of the benzene ring is 4.9 (1)°. This planarity is due, in part, to the presence of a strong intramolecular C-H⋯O hydrogen bond and to two weak C-H⋯O contacts. In the crystal, neighboring molecules are linked by a C-H⋯O hydrogen bond and a C-H⋯π interaction, forming chains along the a-axis direction.

Ethyl 2-[(2-oxo-2H-chromen-7-yl)-oxy]acetate.

Project description:In the title compound, C13H12O5, the mean plane of the 2H-chromene ring system (r.m.s deviation = 0.026 Å) forms a dihedral angle of 81.71 (6)° with the mean plane of ethyl 2-hy-droxy-acetate moiety (r.m.s deviation = 0.034 Å). In the crystal, C-H⋯O hydrogen bonds result in the formation of zigzag layers parallel to the bc plane.

(E)-3,4,5-Trimeth-oxy-N'-[(4-oxo-4H-chromen-3-yl)methyl-idene]benzo-hydrazide.

Project description:In the title chromone-tethered benzohydrazide derivative, C20H18N2O6, the atoms of the E-3-(hydrazonometh-yl)-4H-chromen-4-one segment are essentially coplanar, the largest deviation being 0.065 (6) Å. The dihedral angle between this segment and the benzene ring of the tri-meth-oxy-benzene unit is 40.18 (10) Å. In the crystal, the mol-ecule is linked to its inverse-symmetry equivalent by pairs of N-H⋯O hydrogen bonds and C-H⋯π inter-actions. The -CH=N-NH- segment is stacked on the benzene ring of the chromone unit of a translation-related equivalent mol-ecule [centroid-centroid distance = 3.413 (6) Å].
