| | 4,5-Dimethyl-3-hydroxy-2,5-dihydrofuran-2-one Usage And Synthesis |
| Chemical Properties | clear yellow liquid | | Chemical Properties | 3-Hydroxy-4,5-dimethyl-2(5H)-furanone was found in, for example, fenugreek, coffee, sake, and florsherry.
Its aroma characteristic changes from caramel-like at low concentrations
to curry-like at high concentrations. A method described for its preparation comprises
condensation of ethyl propionate with diethyl oxalate and reaction of the intermediately formed diethyl oxalylpropionate with acetaldehyde. Acidic decarboxylation
of the ethyl 4,5-dimethyl-2,3-dioxodihydrofuran-4-carboxylate gives
the title compound. | | Occurrence | Reported found in roasted Virginia tobacco, beef broth, beer, sherry, botryized wine, coffee, tea, fenugreek,
sake and rice wine. | | Uses | 4,5-Dimethyl-3-hydroxy-2(5H)-furanone-13C3 is a labelled analogue of 4,5-Dimethyl-3-hydroxy-2(5H)-furanone (D473600). 4,5-Dimethyl-3-hydroxy-2(5H)-furanone is a fragrant compound that is a key indicator of maple syrup urine disease, a disorder affecting newborn children that is the result of its inability to properly metabolize Valine (V094205), Leucine (L330110) and Isoleucine (I820175). 4,5-Dimethyl-3-hydroxy-2(5H)-furanone is naturally found in fenugreek seeds, and is an odourant present in sherry wines. | | Definition | ChEBI: Sotolone is a butenolide. It has a role as a metabolite. | | Aroma threshold values | Aroma characteristics at 1.0%; sweet, strong brown, cyclotene and maple like, caramel, toffee, maltol-like
