Descrição geral
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.
