Some naphthoquinone and anthraquinone ketals have been prepared by anodic oxidation. Regioselective hydrolysis of the above diketals into monoketals is also described. Diels-Alder reaction of (E)-1-methoxybuta-1,3-diene with the monoketal of 1,4-dihydro-4,4-dimethoxy-5-benzyloxynaphthalene proceeded in a regioselective manner.
已经通过阳极氧化制备了一些萘醌和蒽醌缩酮。还描述了上述双缩酮的区域选择性水解成单缩酮。(E)-1-甲氧基丁1,3-二烯与1,4-二氢-4,4-二甲氧基-5-苄氧基萘的单缩酮的Diels-Alder反应以区域选择性的方式进行。
