The sonochemical enantioselective hydrogenation of different alpha-ketoesters to the corresponding hydroxy derivatives over cinchona modified Pt catalysts is described. Ultrasonic irradiation was found to be beneficial in improving the optical yields. Besides studying the reaction rates and enantioselectivities, the effect of ultrasonics on the catalyst-modifier system and the scale-up of the process will also be considered.
描述了在金鸡纳修饰的铂催化剂上，不同α-酮酯的声化学对映选择性氢化生成相应的羟基衍生物的过程。发现超声辐照有利于提高光学产率。除了研究反应速率和对映选择性外，还将考虑超声对催化剂-改性剂体系的影响以及该过程的放大。
