α,β-unsaturated carbonyl compounds are organic molecules that contain a carbonyl group (C=O) adjacent to a double bond (C=C). This structure allows for unique reactivity, making them important in various chemical reactions, such as Michael additions and aldol condensations. They are commonly found in natural products and synthetic intermediates. These compounds can be classified into two main categories: enones, which have a carbonyl group at the α position, and enals, where the carbonyl is at the β position. Their reactivity is influenced by the electron-withdrawing nature of the carbonyl group, which stabilizes the conjugated system and enhances nucleophilic attack.
