Method for preparing difluoroallylboronate and application thereof |
| abstract |
The present invention relates to a method for preparing difluoroallylboronate and application thereof, and it belongs to a field of compound preparation. A method for preparing difluoroallyl borate ester is using a compound of the formula II and bis (pinacolato) diboron as raw materials in a solvent and in the presence of an iron catalyst and a base according to the following reaction formula, to obtain a compound of the formula I, n nThe method of the present invention directly use an inexpensive, commercially available metal iron salt as a catalyst to provide a convenient, low-cost method for preparing difluoroallyl borate ester, and provide a new and effective approach for the synthesis of γ-aminobutyric acid receptor agonist (III). |
