A new procedure to obtain anthracene-1,4-diones from p-benzoquinones and myrcene, in the presence of acids, is described. The cycloaddition reaction between α-myrcene and p-benzoquinones, followed by oxidation, led to 1,4-naphthoquinones or 1,4-anthraquinones depending upon whether the Lewis acid used in the Diels-Alder reaction, was present or absent during oxidation; furthermore, traces of acid in
描述了在酸存在下从对苯醌和月桂烯中获得蒽-1,4-二酮的新方法。α-月桂烯和对苯醌之间的环加成反应,然后氧化,导致 1,4-萘醌或 1,4-蒽醌,这取决于在氧化过程中是否存在用于 Diels-Alder 反应的路易斯酸;此外,溶剂中的微量酸在确定所获得的环加合物方面发挥了重要作用。合成的醌对几种肿瘤细胞系表现出细胞毒性。
