2-Meth-oxy-3-[(3,4,5-trimethoxy-anilino)methyl-idene]-3,4-dihydro-2H-1-benzopyran-4-one.

ABSTRACT: The title mol-ecule, C(20)H(21)NO(6), adopts a keto-amine tautomeric form. An intra-molecular N-H?O hydrogen bond, classified as a resonanse-assisted hydrogen bond, influences the mol-ecular conformation; the two benzene rings form a dihedral angle of 24.6?(1)°. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into chains propagating along [001].

N'-[1-(2,4-Dioxo-3,4-dihydro-2H-1-benzopyran-3-yl-idene)eth-yl]thiophene-2-carbo-hydrazide.

Project description:The title compound, C(16)H(12)N(2)O(4)S, was obtained by the condensation of 3-acetyl-4-hy-droxy-coumarin with thien-2-ylcarbonyl hydrazide. The pyran ring adopts a 2,4-dione tautomeric form. The benzopyran ring system is almost coplanar with the thio-phene ring [dihedral angle 0.9?(2)°]. The exocyclic C=C double bond has an E geometry. The mol-ecular conformation is stabilized by an intra-molecular N-H?O hydrogen bond. In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into chains along the a axis.

3,3'-(Ethane-1,2-diyl)bis(6-meth-oxy-3,4-dihydro-2H-1,3-benzoxazine) mono-hydrate.

Project description:The asymmetric unit of the title compound, C(20)H(24)N(2)O(4)·H(2)O, contains one half-organic mol-ecule (an inversion centre generates the other half of the mol-ecule) and a half-mol-ecule of water (the O atom has site symmetry 2). The near planarity of the fused-benzene ring is illustrated by the very small deviations of all the atoms from the plane [largest deviation = 0.0092 (11) Å. The six-membered N,O-containing ring adopts a half-chair conformation. The observed N-CH(2) and CH(2)-O bond lengths can be correlated to the manifestation of an anomeric effect in the N-CH(2)-O unit. In the crystal, the mol-ecules are connected into zigzag chains parallel to [001] through O-H⋯N hydrogen bonds formed between the oxazinic N atom and the solvent water mol-ecule. The chains are consolidated by C-H⋯O inter-actions.

2-Hy-droxy-2-trifluoro-methyl-3,4-dihydro-2H-1-benzopyran-4-one.

Project description:The heterocyclic ring in the title compound, C(10)H(7)F(3)O(3), has a half-boat conformation with the hy-droxy-bearing C atom lying 0.595?(3)?Å out of the plane of the five remaining atoms (r.m.s. deviation = 0.022?Å) in the direction of the hy-droxy O atom. Linear supra-molecular chains along the a axis, sustained by O-H?O hydrogen bonds between the hy-droxy H and ketone O atoms, feature in the crystal packing. These chains are connected into a three-dimensional architecture by C-H?O and C-H?F contacts.
