Sp. Griffiths et al., NOVEL ALKALOID MODIFIERS FOR ENANTIOSELECTIVE HETEROGENEOUS CATALYSIS, Journal of the Chemical Society, Chemical Communications, (21), 1994, pp. 2431-2432
The alkaloids codeine,7,8-dihydrocodeine, brucine and strychnine, when
adsorbed on Pt/silica (EUROPT-1) induce enantioselectivity and enhanc
e the rate of hydrogenation of the carbonyl function in methyl pyruvat
e and in butane-2,3-dione.
