general method has been developed for the synthesis of the tricyclic aromatic ketones 4,12,13 and 14 from the 1-methoxynaphthalenes 8,9,10 and 11 respectively. The transformations of the ketones 4,12,13 and 14 into the diterpene ethers (±)-sempervirol methyl ether (7), (±)-sugiol methyl ether (15), (±)-nimbiol methyl ether (16), and (±)-nimbidiol dimethyl ether (17) have been successfully accomplished
已经开发出一种有效的通用方法,用于分别从1-甲氧基萘8、9、10和11合成三环芳族酮4、12、13和14。酮4,12,13和14转化为二萜醚(±)-间戊四醇甲基醚(7),(±)-苏木醇甲基醚(15),(±)-丁二酚甲基醚(16)和(±)-二丙二醇二甲醚(17)已成功完成,其中涉及在液态氨中进行还原甲基化作为关键反应。
