以邻氯苯甲酸为原料,先进行醚化,再在三氯化铝的作用下进行傅-克反应,可简洁、高效的合成呫吨酮。用硼氢化钠对呫吨酮还原得到呫吨醇。
Chlorobenzoic acid as raw material, the first etherification, and then under the action of aluminum trichloride Fu - grams reaction, can be simple and efficient synthesis of Xanthones. Xanthonyl is reduced with sodium borohydride to give xanthenol.
