| titleOfInvention | Method for preparing large steric hindrance chiral amine by asymmetric palladium catalytic hydrogenation of Z-type large steric hindrance imine |
| abstract | The invention relates to the technical field of chemical industry, in particular to a method for preparing high steric hindrance chiral amine by asymmetric palladium catalytic hydrogenation of Z-type high steric hindrance imine, which comprises the following steps: hydrogenating the Z-type sterically hindered imine represented by the general formula (1) into a sterically hindered chiral amine compound represented by the general formula (2) under the catalysis of a chiral catalyst of palladium in a solvent under certain hydrogen pressure and temperature; the structural formulae of the general formulae (1) and (2) are as follows: the reaction method has mild conditions and simple and convenient operation, can realize good reaction yield and reaction efficiency, and has better application effect. |
