| titleOfInvention | Preparation process of polyhydroxy isoflavone |
| abstract | The invention relates to a preparation method of polyhydroxy isoflavone. The polyhydroxy isoflavone comprises 4',6,7-trihydroxy isoflavone and 3',4',6,7-tetrahydroxy isoflavone. According to the invention, the large-scale preparation of 4',6,7-trihydroxy isoflavone and 3',4',6,7-tetrahydroxy isoflavone can be realized by treating cheap and easily-acquired chemical raw materials including 3,4-dimethoxy phenol, 3,4-dimethoxy benzyl cyanide and hydroxybenzyl cyanide as starting materials through optimal research on Hoesch reaction, carburization n-cyclohexylmaleimide reaction and demethylation protection. The preparation method of polyhydroxy isoflavone disclosed by the invention is economic, efficient, environment-friendly, safe and easy to industrialize. The 4',6,7-trihydroxy isoflavone and the 3',4',6,7-tetrahydroxy isoflavone can be applied to the research and the development of new medicines in the aspects of medicines, food hygiene and the like. |
