General description
Dihydro-4,4-dimethyl-2,3-furandione is an activated keto compound and its enantioselective hydrogenation was reported. Neutral Rhodium (I) aminophosphine-phosphinite complex calatyzed asymmetric hydrogenation of dihydro-4,4-dimethyl-2,3-furandione was reported. Asymmetric hydrogenation of dihydro-4,4-dimethyl-2,3-furandione gives D-(-)-pantoyl lactone, a key intermediate in the synthesis of pantothenic acid.

The combination of ATR-IR and modulation spectroscopy allowed for the study of the interaction of ketopantolactone with Pt/Al2O3 films chirally modified by cinchonidine under hydrogenation conditions. The spectra reveal a significant influence of ketopantolactone on the adsorption of the modifier

A novel enzyme which specifically catalyzes the reduction of conjugated polyketones was purified to homogeneity from cells of Mucor ambiguus AKU 3006. The enzyme has a strict requirement for NADPH and irreversibly reduces a number of quinones such as p-benzoquinone
