  描述：

  8-fluoro-1-hydroxy-5-methoxy-2-naphthaldehyde 在 potassium carbonate 、 三氟乙酸 、 lithium diisopropyl amide 作用下， 以 乙腈 为溶剂， 反应 31.33h， 生成 3-ethoxycarbonyl-4-(8-fluoro-5-methoxy-1-propan-2-yloxynaphthalen-2-yl)but-3-enoic acid

  名称：

  Synthesis of 8-fluororhein

  摘要：

  8-Fluoro-5-methoxy-1-tetralone has been formylated. aromatised and alkylated to give 8-fluoro-1-isopropoxy-5-methoxy-2-naphthaldehyde 11. Condensation of this with a phosphonosuccinate gave, after deprotection, the 4-naphthylbutenoic acid which was cyclised and methylated to give the ethyl 9-fluoro-10-isopropoxy-4,6-dimethoxy-2-carboxylate 12. Removal of the isopropyl group, dichromate oxidation and deprotection gave 8-fluorohein 3, an analogue of the osteoarthritis drug rhein.
