8-diacetoxy-9(10H)-anthracenone with benzoyl chloride and sodium hydride in THF followed by hydrolysis of an intermediate enolester. Furthermore, when benzoyl chloride and DMF were used for the acylation of anthralin, a Vilsmeier-type reaction was observed leading to a novel enamine derivative of anthralin which was hydrolyzed or benzoylated to an enol or enolester, respectively.
