light yellow liqui
Chemical Properties
Abhexone has been found in, for example, lovage and roasted coffee. It has a bouillon-like, coffee and lovage aroma, depending on its concentration. It can be prepared starting from alkyl 2-oxobutanoate either by self-condensation followed subsequently by decarbomethoxylation or by condensation with propionaldehyde and subsequent cyclization . Alkyl 2-oxobutanoate is available from acrylaldehyde and sodium cyanide via alkyl 2-hydroxy-3-butenoate or by reaction of dialkyloxalate with ethyl magnesium bromide . It is used for aromatization of food.
