The hydrogenation of ethyl pyruvate over the cinchonidine-Pt/A1203 catalyst system has been investigated in different solvents. Experimental variables used were as follows: (i) substrate and modifier concentration, (ii) presence of acetic acid, (iii) presence of (R)-ethyl lactate, (iv) mode of intro
