11-Hydroxy-9-(prop-2-en-1-yl)-9,10-dihydro-9,10-propanoanthracen-12-one
In the title compound, C(20)H(18)O(2), the central six-membered ring adopts a boat conformation and the terminal benzene rings make a dihedral angle of 42.66 (4)° with each other. In the crystal structure, the O-H group forms both an intra- and an inter-molecular O-H⋯O hydrogen bond; the former generates an S(5) ring and the latter leads to inversion-generated R(2) (2)(10) loops. The dimers are...

The title chalcone (E)-1-(2-aminophenyl)-3-(benzo[d][1,3]dioxol-5-yl)prop-2-en-1-one was obtained in 76% yield from a NaOH catalyzed Claisen–Schmidt condensation reaction between o-aminoacetophenone and piperonal. This product will be used as a key precursor for the development of an alternative route for the total synthesis of the alkaloid Graveoline. Single crystals of the title compound suit...
متن کاملSynthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone
An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...

In the title mol-ecule, C24H21NO2, the dihedral angle between the carbazole ring system [with a maximum deviation of 0.052 (2) Å] and the benzene ring is 38.6 (1)°. In the crystal, weak bifurcated (C-H)2⋯O hydrogen bonds link the mol-ecules into chains along [100].
متن کامل(E)-3-(Anthracen-9-yl)-1-(2-bromophenyl)prop-2-en-1-one
The mol-ecule of the title chalcone, C(23)H(15)BrO, is not planar and exists in the E configuration with respect to the central C=C bond. The dihedral angle between the benzene and anthracene rings is 83.58 (6)°. The prop-2-en-1-one bridge makes dihedral angles of 63.00 (7) and 42.62 (16)° with the benzene and anthracene rings, respectively. In the crystal, mol-ecules are linked into dimers by ...
