10-Hydroxy-10-(1,3-thiazol-2-ylmethyl)phenanthren-9(10H)-one
In the title phenanthrenone compound, C(18)H(13)NO(2)S, the dihydro-phenanthrene ring system is not planar, with its central ring distorted to a screw-boat conformation. The essentially planar thia-zole ring [maximum deviation = 0.005 (1) Å] is inclined at an inter-planar angle of 23.36 (5)° with respect to the mean plane through the dihydro-phenanthrene ring system. In the crystal packing, int...
متن کاملUnexpected one-pot synthesis of highly conjugated pentacyclic diquinoid compounds.
A new class of pentacyclic diquinoid compounds has been synthesized with a facile one-pot reaction of two molecules of 2-hydroxynaphthoquinone and 1-bromoalkanes in the presence of ferrocene. These molecules were isolated as enol tautomers that exhibit intramolecular hydrogen bond and extended electronic conjugation as proved by the intense absorption spectrum with a broad band between 400 and ...
متن کاملTautomerism in 10-(hydroxyimino)phenanthren-9-one
In the title compound, C(14)H(9)NO(2), a static disorder exists between the keto-oxime and hy-droxy-nitroso tautomers, in an approximate ratio of 4.6:1, based on refined occupancies for disordered parts. No inter-molecular hydrogen bonding is present in the crystal structure. Instead, both tautomers exhibit similar intra-molecular O-H⋯O hydrogen bonds.
متن کامل7-Hydroxy-8-isopropyl-1,1,4a-trimethyl-4a,9,10,10a-tetrahydro-phenanthren-2(1H)-one
The title compound, C(20)H(26)O(2), was isolated from a chloro-form extract of Tetra-clinis articulata wood. The mol-ecule contains three fused rings which exhibit different conformations. The non-aromatic oxo-substituted ring has a screw-boat conformation, while the central ring has a half-chair conformation. In the crystal, mol-ecules are linked to each other by inter-molecular O-H⋯O hydrogen...
متن کامل10-(4-Methylbenzylidene)anthracen-9(10H)-one
In the title compound, C(22)H(16)O, the six-membered ring within the anthrone moiety adopts a shallow boat conformation, with puckering parameters Q = 0.2860 (17) Å, Θ = 99.1 (3)° and Φ = 114.8 (3)°. The dihedral angle between the outer benzene rings is 26.53 (8)°. The mean plane through the anthrone ring system makes a dihedral angle of 38.73 (6)° with the pendant benzene ring. In the crystal,...
