ChEBI: 2-dehydropantolactone is a tetrahydrofurandione. It is functionally related to a pantoic acid. | [Synthesis Reference(s)]
Synthetic Communications, 14, p. 697, 1984 DOI: 10.1080/00397918408063756 | [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. |
