The compound is prepared by base-catalyzed condensation of 1-hydroxyhexane-2,5-dione, a derivative of hydroxymethylfurfural. [2] The structure has been confirmed by X-ray crystallography. [2] Quantum calculations also indicate that the enol is strongly favored relative to the diketo tautomer.
It can also be obtained by dehydration of 4-hydroxy-pentan-2-one using oxalic acid as a catalyst. [5] 3-Penten-2-one occurs naturally in the berries of two species of Aronia melanocarpa. [7] It has also been found in other plants and foods such as tomatoes, cocoa, tea, and potato chips. [5]
Diacetone alcohol is an organic compound with the formula CH 3 C(O)CH 2 C(OH)(CH 3) 2, sometimes called DAA. This colorless liquid is a common synthetic intermediate used for the preparation of other compounds, and is also used as a solvent.

3-Methyl-3-penten-2-one is an unsaturated aliphatic ketone. It is an isomer of mesityl oxide and isomesityl oxide. It is a precursor of 3-methyl-2-pentanone (methyl sec-butyl ketone) and is obtained by acid-catalyzed dehydration of 4-hydroxy-3-methyl-2-pentanone. It is used as an intermediate in organic chemistry syntheses. [1]
2-Methyl-2,4-pentanediol (MPD) is an organic compound with the formula (CH 3) 2 C(OH)CH 2 CH(OH)CH 3. This colourless liquid is a chiral diol . It is produced industrially from diacetone alcohol by hydrogenation . [ 4 ]
