4-(9,10-Dioxo-9,10-dihydroanthracen-1-yl)-4-oxobutanoic acid
In the title compound, C(18)H(12)O(5), the anthracene moiety is almost planar (r.m.s. deviation = 0.0399 Å). In the crystal, mol-ecules are linked to each other by inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonds.
متن کاملSyntheses and antimicrobial activities of amide derivatives of 4-[(2-isopropyl-5-methylcyclohexyl)oxo]-4-oxobutanoic acid
Chiral 4-[(2-isopropyl-5-methylcyclohexyl)oxo]-4oxobutanoic acid reacts with substituted anilines to produce amides 1-6 in high yields. Resulted amides 1-6 were investigated for their antifungal and antibacterial activities. Compounds 2 (96.5%) against Aspergillus fumigatus and 6 (93.7%) against Helminthosporium sativum demonstrated excellent activities. However, compounds 3 (37.6%) against Bac...
متن کامل2-(4-Methylphenyl)quinoline-4-carboxylic acid
In the title compound, C(17)H(13)NO(2), the dihedral angle between the plane of the carb-oxy group and the quinoline mean plane is 45.05 (13)°, and that between the toluene ring mean plane and the quinoline mean plane is 25.29 (7)°. In the crystal, molecules are linked via O-H⋯.N hydrogen bonds, forming chains propagating along the b-axis direction. These chain are linked via C-H⋯O interactions...
متن کامل4-[(2-Fluorophenyl)amino]-4-oxobutanoic acid
The crystal structure of the title compound, C(10)H(10)FNO(3), contains dimers of the asymmetric unit, with R(2) (2)(8) rings arising from inter-molecular O-H⋯O hydrogen bonding through the carboxyl-ate groups. Adjacent dimeric units are connected to each other through one N-H⋯O and two C-H⋯O inter-molecular hydrogen bonds. C-H⋯O hydrogen bonds involving the aromatic ring and the O atoms of two...
متن کامل4-[(4-Bromophenyl)amino]-2-methylidene-4-oxobutanoic acid
In the title compound, C11H10BrNO3, two independent mol-ecules (A and B) crystallize in the asymmetric unit. The dihedral angles between the mean planes of the 4-bromo-phenyl ring and amide group are 24.8 (7) in mol-ecule A and 77.1 (6)° in mol-ecule B. The mean plane of the methyl-idene group is further inclined by 75.6 (4) in mol-ecule A and 72.5 (6)° in mol-ecule B from that of the amide gro...
