title: Sonochemical asymmetric hydrogenation of isophorone on proline modified Pd/Al2O3 catalysts.
abstract: The sonochemical asymmetric hydrogenation of isophorone (3,3,5-trimethyl-2-cyclohexenone) by proline-modified Pd/Al2O3 catalysts is described; presonication of a commercial Pd/Al2O3-proline catalytic system resulted in highly enhanced enantioselectivities (up to 85% ee).
