Utility of 3-Acetyl-6-bromo-2H-chromen-2-one for the Synthesis of New Heterocycles as Potential Antiproliferative Agents.
Coumarin derivatives containing pyrazolo[1,5-a]pyrimidine, tetrazolo[1,5-a]pyrimidine, imidazo[1,2-a]pyrimidine, pyrazolo[3,4-d]pyrimidine, 1,3,4-thiadiazoles and thiazoles were synthesized from 6-bromo-3-(3-(dimethylamino)acryloyl)-2H-chromen-2-one, methyl 2-(1-(6-bromo-2-oxo-2H-chromen-3-yl)ethylidene)hydrazine carbodithioate, 2-(1-(6-bromo-2-oxo-2H-chromen-3-yl)ethylidene) hydrazine carbothi...
متن کامل3-Acetyl-4-hydroxy-6,7-dimethyl-2H-chromen-2-one
In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047 (1) Å]. An intra-molecular hydrogen bond is observed between the hy-droxy and the ketonic O atoms. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers. Additional inter-molecular C-H⋯O hydrogen bonds further inter-...
متن کامل(E)-6-Bromo-3-{2-[2-(4-chlorobenzylidene)hydrazinyl]thiazol-5-yl}-2H-chromen-2-one
In the title compound, C(19)H(11)N(3)O(2)SClBr, the chromene ring system and the thia-zole ring are each approximately planar, with maximum deviations of 0.033 (3) Å and 0.006 (3) Å, respectively. The mol-ecule adopts an E configuration about the central C=N double bond. The central thia-zole ring makes dihedral angles of 9.06 (14)° and 12.07 (11)° with the chloro-substituted phenyl ring and th...
متن کامل3-(2-Amino-1,3-thiazol-4-yl)-6-bromo-2H-chromen-2-one
The mol-ecule of the title compound, C(12)H(7)BrN(2)O(2)S, is essentially planar with a maximum deviation of 0.234 (3) Å from the mean plane through all non-H atoms. The dihedral angle between the coumarin ring plane and that of the five-membered thia-zole ring is 12.9 (1)°. In the crystal, strong N-H⋯O, N-H⋯N and weak but highly directional C-H⋯O hydrogen bonds provide the links between the mo...
متن کامل3-(2-Bromoacetyl)-6-fluoro-2H-chromen-2-one
The non-H atoms of the title compound, C(11)H(6)BrFO(3), are essentially coplanar (r.m.s. deviation for all non-H atoms = 0.074 Å). In the crystal, the molecules are linked by C-H⋯O and C-H⋯Br inter-actions.
