Ethyl 2-hydroxy-5-oxo-4-phenyl-2,3,4,5-tetrahydropyrano[3,2-c]chromene-2-carboxylate
The main structural unit of the title compoud, C(21)H(18)O(6), is a fused three-ring group consisting of coumarin and tetra-hydro-pyrane ring systems. Two C atoms of the tetra-hydro-pyran ring are displaced by 0.295 (3) and -0.360 (2) Å from the mean plane of coumarin ring. The dihedral angle between the phenyl and coumarin rings is 73.94 (3)°. Inter-molecular O-H⋯O hydrogen bonds are present i...
متن کاملEthyl 2-amino-4-(4-methyl-1,3-thiazol-5-yl)-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carboxylate
There are two independent mol-ecules in the asymmetric unit of the title compound, C19H16N2O5S, in which the thia-zole rings make dihedral angles of 80.89 (11) and 84.81 (11)° with the pyrano[3,2-c]chromene ring systems. An intra-molecular N-H⋯O hydrogen bond involving the amino group occurs in each independent mol-ecule. In the crystal, the amino groups are involved in N-H⋯O and N-H⋯N hydrogen...
متن کاملEthyl (2S,4R)-4-(4-bromophenyl)-2-hydroxy-5,10-dioxo-3,4,5,10-tetrahydro-2H-benzo[g]chromene-2-carboxylate
In the crystal structure of the title compound, C(22)H(17)BrO(6), the quinone ring makes a dihedral angle of 81.84 (3)° with the benzene ring. The chiral C atoms, viz. the ring C atoms bearing the hydr-oxy and bromo-phenyl substituents, exhibit R and S configurations, respectively. The terminal ethyl group of the -CO(2)CH(2)CH(3) group is disordered over two sets of sites with site-occupancy fa...
متن کاملEthyl 5-(4-chlorophenyl)-2-[(Z)-(methoxycarbonyl)methylene]-7-methyl-3-oxo-3,5-dihydro-2H-thiazolo[3,2-a]pyrimidine-6-carboxylate
The title compound, C(19)H(17)ClN(2)O(5)S, was synthesized by the reaction of ethyl 6-(4-chloro-phen-yl)-2-mercapto-4-methyl-1,6-dihydro-pyrimidine-5-carboxyl-ate and dimethyl acetyl-ene-dicarboxyl-ate in methanol. In the mol-ecule, the nearly planar thia-zole ring, with a mean deviation from the plane of 0.0108 (3) Å, is fused with a dihydro-pyrimidine ring in a flattened half-chair conformation.
