The influence of the reaction conditions on the asymmetric heterogeneous cascade reaction of 2-nitrophenylpyruvates over Pt catalysts modified with cinchonidine leading to (R)-3-hydroxy-3,4-dihydroquinolin-2(1H)-one derivatives has been studied. Results of studies on the amount of aceticacid or catalyst, nature of the Pt support, kinetic examinations, effect of H2 pressure, and modifier and substrate
