Synthesis route :
Acetoin is synthesized by a partial oxidation of 2,3-butanediol.
Synthesis precursor :
Acetoin is not a precursor to the synthesis of another compound of olfactory interest.
Isomerism :
Acetoin has an asymmetric carbon. Its two enantiomers (R) and (S) have a similar smell. In perfumery, it is the racemic mixture of this molecule that is used.
Ethyl acetate is a constitutional isomer of Acetoin. These two molecules, however, have a very different smell, as Ethyl acetate has a solvent smell and is more fruity.
