| titleOfInvention | Synthetic method of natural product pterostilbene |
| abstract | The invention provides a synthetic method of natural product pterostilbene, and is mainly used for solving the problems of high cost, low yield and non-adaptability for large-scale industrial production of the existing pterostilbene preparing method. The synthetic method of pterostilbene comprises the following steps of: 1) preparing an intermediate toluylene; 2) preparing 3,5-dialkyl-4-O-tetrahydropyrane toluylene; 3) preparing the pterostilbene. According to the invention, as HBr is adopted for a bromination reaction, the preparation of 3,5-dimethoxybenzylbromide is mild in reaction conditions, simple in aftertreatment and low in cost, and the yield is above 90%; the whole process is simple to operate, easy in obtaining of raw materials, and applicable for industrial production. |
