2-(4-Methoxyphenyl)-1H-indene
Excluding four H atoms, the molecule of the title compound, C(16)H(14)O, is almost planar, with an r.m.s. deviation of 0.0801 (2) Å. Due to p-π conjugation, the lengths of the two single bonds attached to the O atom are significantly different.
متن کاملEthyl 2-(4-methylbenzoyl)-2,3-dihydro-1H-indene-2-carboxylate
The title compound, C20H20O3, contains two fused rings with a quaternary carbon centre connecting p-toluoyl and eth-oxy-carbonyl groups. The dihedral angle between the fused benzene ring and the three-C-atom plane (derived from O=C-C-C=O) is 82.5 (4)°, whereas the dihedral angle between the planes of the benzene rings is 53.4 (2)°. In the crystal, molecules are linked via C-H⋯Oester hydrogen bo...
متن کاملCrystal structure of 2-(5-bromo-2-hydroxybenzylidene)-2,3-dihydro-1H-indene-1,3-dione
The title mol-ecule, C16H9BrO3, deviates slightly from planarity. The benzene ring makes a dihedral angle of 1.02 (9)° with the plane defined by the five-membered ring of the indandione moiety. The latter exhibits a minute twist indicated by the dihedral angle of 0.47 (9)° between the planes of the five- and six-membered rings. An intra-molecular C-H⋯O hydrogen bond between the attached benzene...
متن کاملCrystal structure of 2-hydroxy-2-(2-oxocycloheptyl)-2,3-dihydro-1H-indene-1,3-dione
In the title compound, C16H16O4, the five-membered ring of the indene-1,3-dione unit adopts a twist conformation, whereas the seven-membered ring adopts a twist-chair conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, weak C-H⋯O hydrogen bonds and π-π stacking [centroid-to-centroid distance = 3.7373 (8) Å] into a three-dimensional supra-molecular architecture.
متن کاملAsymmetric synthesis of (7aS)-7a-methyl-4,5,7,7a-tetrahydro-1H-indene-2,6-dione and useful derivatives thereof.
The enantioselective synthesis of the title compound, using Meyers' bicyclic lactam methodology, is described. This compound and a few of its derivatives are useful intermediates in natural product synthesis.
