                                A convergent approach to substituted phenanthrenes via quinol ketals
                             
                            
                                摘要:
                                Reaction of 2'-lithiostyrenes with p-benzoquinone monoketals gives p-quinol ketals which undergo Lewis acid-catalyzed cyclization and aromatization, affording 2-methoxyphenanthrenes.
