| titleOfInvention | Method for selectively preparing α -acyloxy or β -acyloxy products of enaminone compounds |
| abstract | The invention relates to a method for selectively preparing α -acetoxylation or β -acetoxylation products of an enaminone compound, which comprises the steps of adding the enaminone compound and PIDA into trifluoroethanol according to the proportion of 1.0: 1.3 during selective preparation of α -acetoxylation products of the enaminone compound, stirring for 0.5-3 hours at room temperature to obtain the product, adding the enaminone compound and the PIDA into a reaction vessel according to the proportion of (1: 1) - (1: 2) during selective preparation of β -acetoxylation products of the enaminone compound, adding water and a solvent, and stirring for 3-6 hours at room temperature to obtain the product, wherein the process is simple, the reaction conditions are mild, α -acetoxylation products of the enaminone compound can be effectively obtained at high yield, and β -acetoxylation of the enaminone compound can be selectively rearranged to obtain β -acetoxylation α -unsaturated amide compounds. |
