  Structure and synthesis of arnottin I: a 6H-benzo[d]naphtho[1, 2-b]pyran-6-one derivative from a plant source

  摘要：

  Arnottin I 2 isolated from Xanthoxylum arnottianum Maxim and of previously unknown structure has been unambiguously synthesized utilizing a 2-methylarenofuran as a masked salicylaldehyde. This is the first occurrence of a 6H-benzo[d]naphtho[1,2-b]pyran-6-one derivative, the same skeleton as that of gilvocarsin-type antibiotics showing antitumour activity, from a plant source.

  Nitrosation of 3-methoxyphenol and 1-naphthol were examined under both acidic (NaNO(2)-EtCO(2)H-H(2)O) and basic (i-AmNO(2)-K(2)CO(3)-DMF) conditions. Acidic nitrosations afforded ortho-directed products, whereas para-directed nitrosations were observed under basic conditions to yield p-quinone monooximes. The basic para-directed nitrosation was further examined using 15 phenols, two naphthols, and

  在酸性（NaNO（2）-EtCO（2）HH（2）O）和碱性（i-AmNO（2）-K（2）CO（3）-DMF下都检查了3-甲氧基苯酚和1-萘酚的亚硝化） 条件。酸性亚硝化提供了邻位定向的产物，而在碱性条件下观察到对位亚硝化可生成对醌单肟。使用15个酚，两个萘酚和四个酚杂环进一步检查了基本的对位亚硝化反应。一锅操作进行基本亚硝化，然后用硫酸二甲酯进行甲基化，可以高收率得到相应的甲基醚。衍生自3-甲氧基苯酚和8-羟基喹啉的两种对醌单肟对HSV-1具有中等活性，后一种肟对HSV-2也有效。另一方面，对苯二酚单肟衍生自水杨酸甲酯，1-萘酚，
