متن کاملSynthesis 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" BISCYCLISATION" SYNTHESIS OF 1,8-DIHYDROXY-9, 1 0- ANTHRAQUINONE (1,8-DHA)
The synthetic route in this work is based on the classical Friedel-Crafts strategy, and began with 1,4-dimethoxybenzene (I), followed by alkylation and selective demethylation of 2-methoxy function in 0x0-acid (3). The orthoformylation to synthesize aldehyde (6) was based on the Reimer-Tieman reaction. Chain extension of this aldehyde required methylation of the hydroxyl group and condensat...
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 solar neutrino oscillations, if ν e has a significant third massive component, the allowed parameter space in ∆m 2 and sin 2 2θ for the first two components is shown to be greatly increased. This third component may be correlated to atmospheric neutrino oscillations, as shown in a specific predictive seesaw model of the 3 × 3 neutrino mass matrix. Possible variations to include the recent LS...
