Chemische Studien uber naturliche Anthrachinone. II. Synthese von Citreoroseine, Fallacinol und Fallacinal

Abstract

The meltingpoint and infrared spectrum of synthesized 1, 6, 8-trihydroxy-3-hydroxymethylanthraquinone (II) were identical with those of citreoroseine (I) [ω-hydroxyemodin)-III)]. Synthesis of 1, 3-diacetoxy-3-bromomethyl-6-methoxyanthraquinone (VIII) was established. And fallacinal (V) could be prepared by oxidation of fallacinol (IV).
