| titleOfInvention | Preparation method of polysubstituted aryl ethylene boronic acid pinacol ester derivative |
| abstract | The invention discloses a preparation method of a polysubstituted aryl ethylene boronic acid pinacol ester derivative, belonging to the technical field of chemical preparation. In the method, under an inert atmosphere, firstly adding alkali and diaryl high-valence iodine compounds, then adding a vinyl boronic acid pinacol ester compound, a solvent and deionized water for reaction, and after the reaction is finished, sealing, cooling, separating and purifying to obtain a polysubstituted aryl ethylene pinacol ester derivative; the reaction condition is mild, a transition metal catalyst is not needed, the product yield is high, and the industrial popularization is easy. |
