Synthesis of 1,2,3,4,5,6,7,8-Octahydro-9-Ethoxy-10-Hydroxy-1-Anthracenone[OEHA]
Anthralin and some of its derivatives have implied antipsoriatic effect in clinical and pharmaceutical studies. Anthralin is synthesized by different strategies. In this work we report the synthesis of "OEHA" as a precursor of another biological active compound.
متن کامل(7-Dimethylamino-1-hydroxy-3-naphthyl)(morpholino)methanone
In the title compound, C(17)H(20)N(2)O(3), the morpholine ring is in a slightly distorted chair form. The crystal structure is stabilized by an inter-molecular O-H⋯O hydrogen bond between the H atom of the hydroxyl group and the O atom of a neighbouring carbonyl group. A weak inter-molecular C-H⋯π inter-action is also present.
متن کامل(4-Chlorophenyl)(2-hydroxy-7-methoxynaphthalen-1-yl)methanone
The title compound, C(18)H(13)ClO(3), has an intra-molecular O-H⋯O=C hydrogen bond between the carbonyl group and the hydr-oxy substituent on the naphthalene ring system. The angle between the C=O bond plane and the naphthalene ring system is relatively small [20.96 (8)°]. The angle between the benzene ring and the carbonyl group is rather large [35.65 (9)°] compared to that in an analogous com...
متن کاملSynthesis and antibacterial activities of novel 4-hydroxy-7-hydroxy- and 3-carboxycoumarin derivatives.
Coumarin derivatives are used as fluorescent dyes and medicines. They also have some notable physiological effects, including the acute hepatoxicity and carcinogenicity of certain aflatoxins, the anticoagulant action of dicoumarol, and the antibiotic activity of novobicin and coumerymycin A1. Because the number of drug resistant strains is increasing at present, the synthesis of new antibacteri...
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...
