Authors: not saved
Abstract:
An efficient synthesis of the 1,l'-dihydroxy-2,2'-(thiodimethy1ene)bis-9(10H)- anthrone (5) is described. Reaction of 1 -methoxy-2-(bromomethy1)-9,lOanthraquinone (1) with excess sodium sulfide in ethanol, demethylation to the corresponding hydroxy and subsequent selective reduction produced the title compound in high yield.

10-bromo-1,8-dihydroxy-9-anthrone (10-bromoanthralin) was synthesized with precise ratio of bromine to anthralin (1.10:1), respectively. With this ratio of the reagents, the reaction is repetitive at any scale. This compound is a highly significant intermediate for the synthesis of many anthralin derivetised antipsoriatic drugs. Bromination at both benzylic and aromatic ring positions of anthra...

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

The synthesis of 1,5-dihydroxy-9,10-anthraquinone (17); (1,5-DHA) was accomplished during, attempts towards the synthesis one of its derivatives called anthralin (1,8-dihydroxy-9-anthrone) which is known as an antipsoriasis drug since 1916 [1]. This work is a new reigiospecilic preparation of 1,5-DHA based on Friedel-Crafts reaction starting from 1,4-dimethoxybenzene. This synthetic route, ...

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...

Epoxy resin of 9,9'-bis-(3,5-dibromo-4-hydroxyphenyl) anthrone-10 (EANBr, EEW 490) was synthesized and was characterized by IR and 1HNMR . EANBr and EPK3251 cured resin (EANBrC) were characterized by DSC and TGA at 10°Cmin-1 under nitrogen atmosphere. Broad DSC endothermic transitions of EANBr (265.3 °C) and EANBrC (291.4 °C) are due to some physical change and further confirmed by no weight lo...
