Descrição:4-Methoxy-3-buten-2-one is a chemical compound with the molecular formula CH3OCH=CH(CH3)COCH3. It is a colorless liquid that has a pleasant, fruity odor. This chemical can be obtained by reacting anilines with acetoacetic ester in the presence of pyridine. The reaction mechanism for this reaction is nucleophilic attack by the nitrogen on the carbonyl carbon of the acetoacetic ester, followed by protonation and release of methanol.
The methoxy group is a nucleophile that attacks the electrophilic enolate carbon of acetoacetic ester to form an enolate ion. The anion formed after protonation is attacked by methanol, forming 4-methoxy-3-buten-2-one.
This chemical can also be prepared from fatty acids through a process called saponification: in
