From an endophytic fungus, a close relative of Talaromyces sp., found in association with Cedrus deodara, four compounds including two new ones (2 and 4) were isolated and characterized. The structures of two compounds (1 and 4) were confirmed by X-ray crystallography. The compounds displayed a range of cytotoxicities against human cancer cell lines(More)
In the title compound, C(8)H(10)ClN(3)O(2)S, the oxadiazinane ring is in a sofa conformation with the ring O atom deviating from the best plane of the remaining five atoms by 0.636 (2) Å. A short intra-molecular C-S⋯O=C contact [S⋯O 3.122 (2) Å, C-S⋯O 80.0 (2)°] is observed between the two mol-ecular fragments bridged by the methyl-ene group. In the(More)
In the title mol-ecule, C19H18F3N3O, the dihydro-pyridine and cyclo-hexene rings both adopt sofa conformations. The five essentially planar atoms of the dihydro-pyridine ring [maximum deviation = 0.039 (2) Å] form a dihedral angle of 88.19 (8)° with the benzene ring. The F atoms of the trifluoro-methyl group were refined as disordered over two sets of sites(More)
In the title compound, C13H13NO3·H2O, the dihedral angle between the ethyl ester group [C-C-O-C(=O); maximum deviation = 0.003 (2) Å] and the quinoline ring system is 7.94 (12)°. The water solvent mol-ecule is linked to the title mol-ecule via O-H⋯O and O-H⋯N hydrogen bonds. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains(More)
In the title compound, C(24)H(27)BrN(4)O(4)S(2), the mol-ecule is twisted at the sulfonyl S atom with a C-S(O(2))-N(H)-C torsion angle of 62.6 (3)°. The benzene rings bridged by the sulfonamide group are tilted to each other by a dihedral angle of 60.6 (1)°. The dihedral angle between the sulfur-bridged pyrimidine and benzene rings is 62.7 (1)°. The(More)
In the title compound, C(29)H(22)F(2)O(2)S, the central benzene ring makes dihedral angles of 45.83 (7), 38.90 (7) and 55.50 (7)° with the two fluoro-substituted benzene rings and the methyl-sulfanyl-substituted benzene ring, respectively. In the crystal, C-H⋯O contacts connect the mol-ecules into layers lying perpendicular to the c axis. In addition, π-π(More)
In the title mol-ecule, C(9)H(10)ClN(3)O, the dihedral angle between the pyridine ring and imidazoline ring mean plane [maximum deviation = 0.031-(3) Å] is 76.2 (1)°. In the crystal, N-H⋯O hydrogen bonds link pairs of mol-ecules to form inversion dimers. In addition, weak C-H⋯N hydrogen bonds and π-π stacking inter-actions between pyridine rings(More)
The title compound, C(9)H(12)ClN(4) (+)·Cl(-), is a natural metabolic product of imidacloprid [systematic name: (E)-1-(6-chloro-3-pyridyl-meth-yl)-N-nitro-imidazolidin-2-yl-idene-amine] and was obtained by the reduction of the latter using Fe in HCl. The dihedral angle between the pyridine and imidazole rings is 62.09 (12)°. The crystal structure is(More)
In the title mol-ecule, C(17)H(13)FN(2)O(2), the 3,4-dihydro-pyrimidine ring adopts a flattened sofa conformation with the flap atom (which bears the fluoro-phenyl substituent) deviating from the plane defined by the remaining five ring atoms by 0.281 (2) Å. This plane forms dihedral angles of 85.98 (6) and 60.63 (6)° with the 4-fluoro-phenyl and(More)
