11-tetrahydro-7H-cycloocta[de]naphthalene ring system is described. Reaction of diethyl acetonedicarboxylate and 1,8-bis(bromomethyl)naphthalene gave the eight-membered pericyclized compound, diethyl 9-oxo-8,9,10,11-tetrahydro-7H-cycloocta[de]naphthalene-8,10-dicarboxylate, which was then converted, through several steps, into various kinds of 8- and 10-methyl-substituted 8,9,10,11-tetrahydro-7H-cycloocta[de]naphthalenes
描述了一种用于合成 8,9,10,11-四氢-7H-环辛 [de] 萘环系的新型便捷方法。丙酮二甲酸二乙酯和 1,8-双(溴甲基)萘反应得到八元环化合物,9-氧代-8,9,10,11-四氢-7H-环辛[de]萘-8,10-二甲酸二乙酯然后通过几个步骤将其转化为各种 8-和 10-甲基取代的 8,9,10,11-四氢-7H-环辛[de]萘及其 9-氧代衍生物,以及未取代的化合物,8,9,10,11-四氢-7H-环辛[de]萘和8,9,10,11-四氢-7H-环辛[de]萘-9-one。烃,8,8,10,10-四甲基-8,9,10,11-四氢-7H-环辛[de]-萘由8,8,10,10-四(甲苯磺酰氧基甲基)-8,9制备,10,11-四氢-7H-环辛[de]萘。
