| titleOfInvention | Preparation method of 7-hydroxy-1-tetralone |
| abstract | The invention relates to a preparation method of 7-hydroxy-1-tetralone with a structural formula I, which takes 4- (4-methoxyphenyl) butyric acid with a structural formula II as a starting material and is carried out in Lewis acidIn the presence of (a), performing ring closing and demethylation reaction by a one-pot method to obtain the 7-hydroxy-1-tetralone. The preparation method provided by the invention is simple and convenient to operate, does not use a phosphorus-containing reagent, and improves the environmental friendliness of the reaction; in addition, the yield of the 7-hydroxy-1-tetralone is high (> 85 percent), and the purity is good (> 99.9 percent). Therefore, the method is completely suitable for industrial production and meets the quality requirement of the medical industry on the intermediate. |
