Methyl 7-methoxy-9-oxo-9H-xanthene-2-carboxylate
The crystal structure of the title compound, C(16)H(12)O(5), is stabilized by C-H⋯O hydrogen bonds and C=O⋯π inter-actions; π-π inter-actions are also present. With respective average deviations from planarity of 0.003 (2) and 0.002 (1) Å, the xanthone and ester fragments are oriented at an angle of 2.8 (2)° with respect to each other. The mean planes of the xanthone skeleton lie either paralle...
متن کامل10-Methyl-9-phenoxycarbonylacridinium trifluoromethanesulfonate monohydrate
In the crystal structure of the title compound, C(21)H(16)NO(2) (+)·CF(3)SO(3) (-)·H(2)O, the anions and the water mol-ecules are linked by O-H⋯O inter-actions, while the cations form inversion dimers through π-π inter-actions between acridine ring systems. These dimers are linked by C-H⋯O and C-F⋯π inter-actions to adjacent anions, and by C-H⋯π inter-actions to neighboring cations. The water m...
متن کامل10-Methyl-9-(2-nitrophenoxycarbonyl)acridinium trifluoromethanesulfonate
The crystal structure of the title compound, C(21)H(15)N(2)O(4) (+)·CF(3)O(3)S(-), is stabilized by C-H⋯O and C-H⋯F hydrogen bonds, by C-F⋯π, N-O⋯π and S-O⋯π inter-actions, and by O⋯O [2.70 (4) Å] and O⋯F [2.85 (1) or 2.92 (1) Å] contacts; π-π interactions are also present. In the packing of the mol-ecules, acridine units are either parallel or inclined at an angle of 12.5 (1)°. The nitrophenox...
متن کاملMethyl 3β-methoxycarbonyloxy-4,4-dimethyl-17-oxo-16α-(3-oxobutyl)-16β-carboxylate
The title steroid, C(29)H(44)O(7), is a new androgen derivative and a key inter-mediate for synthesizing novel anti-HIV steroid agents. There are four trans-fused rings in the structure. The three six-membered rings exhibit chair conformations, while the five-membered ring adopts an envelope conformation.
متن کاملCrystal structure of methyl endo-8-cyano-exo-8-methyl-3-oxo-2-oxabicyclo[2.2.2]oct-5-ene-6-carboxylate.
A photochemical cycloaddition reaction of methyl 2-pyrone-5-carboxylate with methacrylonitrile mainly gave a [4 + 2] cycloadduct, assigned as methyl endo-8-cyano-exo-8-methyl-3-oxo-2-oxabicyclo[2.2.2]oct-5-ene-6-carboxylate, whose structure was determined by an X-ray diffraction study. The formation of the cycloadduct was reasonably explained by considering a biradical intermediate having a les...
