1,3,5,8-Tetrahydroxy-2-methylanthraquinone (I) and its 3-O-β-D-glucopyranoside (II) have been synthesised.Condensation of 3,6-dihydroxyphthalic anhydride (IV) with 2,6-dihydroxytoluene (V) in the presence of anhyd.AlCl3 followed by cyclisation of the resultant o-benzoylbenzoic acid derivative (III) with sulphuric acid containing boric acid gives the anthraquinone I.Treatment of I with acetobromoglucose in alkaline medium followed by deacetylation furnishes the glycoside (II).
