simple method for the preparation of various arylnaphthalene lactone natural products was developed and used to synthesize diphyllin (10), justicidin A (12), cilinaphthalide B (13), taiwanin E (15), chinensinaphthol (16), taiwanin E methyl ether (17), chinensinaphthol methyl ether (18), justicidin C (21) and justicidin D (22). The syntheses proceeded via HauserKraus annulation of cyanophthalides (7a
本研究开发了一种制备各种芳基萘内酯天然产物的新型简便方法,并将其用于合成双叶素 (10)、justicidin A (12)、西萘啶 B (13)、台湾宁 E (15)、茚苁醇 (16) ), taiwanin E 甲基醚 (17), chinensinaphthol 甲基醚 (18), justicidin C (21) 和 justicidin D (22)。合成通过氰基苯酞(7a 和 7b)的 Hauser-Kraus 环化和具有磺酸盐基团的芳基萘内酯(9、14、19 和 20)与相应的芳基三氟硼酸钾的 Suzuki-Miyaura 交叉偶联进行。
