| 英文摘要 | enantioselective hydrogenation of isophorone (3,5,5-trimethyl-2-cyclohexenone) over (s)-proline modified pd catalysts has been studied. both the pd particle size and the acid-base properties of the support influenced the hydrogenation reaction of isophorone and the subsequent kinetic resolution of 3,3,5-trimethylcyclohexanone (tmch). this was explained by assuming the reaction pathway as a consequential process. the rapid hydrogenation of isophorone initially yielded racemic tmch, and then the slow kinetic resolution consumed the (r)-tmch, leaving (s)-tmch in excess. most promisingly, the pd/mgo catalyst with enhanced adsorption of proline and moderate pd particle sizes resulted in high enantioselectivity (ee of 95%) and 43% yield of tmch.
