Abstract
The sonochemical enantioselective hydrogenation of different alpha-ketoeste rs to the corresponding hydroxy derivatives over cinchona modified Pt catal ysts is described. Ultrasonic irradiation was found to be beneficial in imp roving the optical yields. Besides studying the reaction rates and enantios electivities, the effect of ultrasonics on the catalyst-modifier system and the scale-up of the process will also be considered.
