4-Azidomethyl-7-methyl-2-oxo-2H-chromene-6-sulfonyl azide
In the title compound, C(11)H(8)N(6)O(4)S, the plane of the coumarin aromatic ring is twisted by 17.2 (2)° with respect to the plane of the azide group bound to the methyl-ene substituent, whereas it is twisted by 83.2 (2)° to the plane of the azide attached to the sulfonyl group. The crystal structure is stabilized by weak C-H⋯O inter-actions, leading to the formation of dimers with R(2) (2)(1...
متن کاملMethyl 2-oxo-2H-chromene-3-carboxylate
The title compound, C(11)H(8)O(4), features an almost planar mol-ecule (r.m.s. deviation = 0.033 Å for all non-H atoms). In the crystal, the mol-ecules are linked via C-H⋯O hydrogen bonds, forming two-dimensional networks lying parallel to (1-21).
متن کامل6-Chloro-7-methyl-4-oxo-4H-chromene-3-carbaldehyde
In the title compound, C11H7ClO3, a chlorinated and methyl-ated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0670 Å), with the largest deviation from the least-squares plane [0.2349 (17) Å] being for the pyran carbonyl O atom. In the crystal, mol-ecules are linked through π-π stacking inter-actions along the a axis [centroid-centroid distance betw...
متن کاملCrystal structures of 4-methyl-2-oxo-2H-chromene-7,8-diyl diacetate and 4-methyl-2-oxo-2H-chromene-7,8-diyl bis(pent-4-ynoate)
In the structures of the two title coumarin derivatives, C14H12O6, (1), and C20H16O6, (2), one with acetate and the other with pent-4-ynoate substituents, both the coumarin rings are almost planar. In (1), both acetate substituents are significantly rotated out of the coumarin plane to minimize steric repulsions. One acetate substituent is disordered over two equivalent conformations, with occu...
متن کامل4-Methyl-2-oxo-2H-chromen-7-yl 4-methoxybenzenesulfonate
In the title compound, C(17)H(14)O(6)S, the 2H-chromene ring is essentially planar, with a maximum deviation of 0.016 (1) Å. The dihedral angle between the 2H-chromene and the benzene rings is 54.61 (5)°. The C atom of the meth-oxy group is close to coplanar with its attached ring [deviation = 0.082 (2) Å]. In the crystal, mol-ecules are connected via C-H⋯O hydrogen bonds, forming sheets lying ...
