Alkyl-substituted polyarenes of the formula ##STR1## in which R is alkyl and Ar.sub.res is an aryl residue, are prepared from aryl ketones by reaction of the latter with 1-cyclohexenyloxytrimethylsilane in the presence of a Friedel-Crafts catalyst. When R is methyl and Ar.sub.res is a naphthyl residue, the reaction serves as a step in a reaction scheme leading to crisnatol mesylate, a pharmaceutical useful in the treatment of brain cancer.
公式为##STR1##的烷基取代聚
芳烃,其中R为烷基,Ar.sub.res为芳基残基,通过在Friedel-Crafts催化剂存在下,将芳基酮与1-环己氧基三甲基
硅烷反应制备而成。当R为甲基且Ar.sub.res为
萘基残基时,该反应可作为反应方案中的一步,用于制备可用于治疗脑癌的克里斯纳托尔
甲磺酸盐药物。
