Synthesis of 1,5-Dihydroxy-9,10-Anthraquinone
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, ...

متن کاملIridoids and anthraquinones from the Malaysian medicinal plant, Saprosma scortechinii (Rubiaceae).
A further investigation of the leaves and stems of Saprosma scortechinii afforded 13 compounds, of which 10 are new compounds. These were elucidated as the bis-iridoid glucosides, saprosmosides G (1) and H (2), the iridoid glucoside, 6-O-epi-acetylscandoside (3), and the anthraquinones, 1-methoxy-3-hydroxy-2-carbomethoxy-9,10-anthraquinone (4), 1-methoxy-3-hydroxy-2-carbomethoxy-9,10-anthraquin...

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...
