What it is Filled
An organic compound containing a ketone group conjugated with a carbon-carbon double bond, the alpha,beta-unsaturated ketone motif, found in natural products, steroids such as 3-oxo-delta-4 and 3-oxo-delta-1 steroids including testosterone and progesterone, cyclohexenones, and in synthetic intermediates; enones are Michael acceptors and undergo characteristic conjugate additions, cycloadditions and photochemical reactions.
Why it exists Filled
Let an agent explain enones and their reactivity, relay chemistry and examples from organic chemistry references, describe their role in steroids and natural products, and distinguish enones from simple ketones, enals, enols and unconjugated unsaturated ketones.
Distinguishing features Filled
- Conjugation
- Michael acceptor
- Steroid motif
- Synthetic building block
What robots and AI may and may not do Filled
Must not
- Give synthesis procedures for regulated steroids or other controlled enone compounds.
- Present a reactive enone as safe to handle without regard to its hazard data.
- Confuse an obscure systematic compound name with a familiar one.
- Advise anyone on using steroid hormones without a prescription.
Only with a human decision
- Laboratory work with reactive or controlled enone compounds.
May
- Explain the enone motif and how it differs from enols and enals.
- Name natural products and steroids that contain enones.
Moral aspects Filled
- Some enones are irritants and sensitisers that harm workers.
- Steroid enones are misused for doping and without medical oversight.
Who is affected
- Laboratory workers
- Athletes

Recognition required Filled
- An enone contains a ketone conjugated with a C=C double bond.
- Examples include the 3-oxo steroids, cyclohexenones and hydroxy-oxo-heptadienoic acids named in the aliases.
- Enals are aldehydes, enols have OH on a double bond, and simple ketones lack conjugation.

- relay reactivity
- describe examples
- distinguish related classes
Hazards and failure modes required Filled
- Confusing enones with enols or enals
- Registry aliases naming obscure specific compounds
- Reactivity hazards of some enones
Standards and interfaces required Filled

- Chemical safety rules for reactive Michael acceptors
Context of use required Filled
- Not applicable; a class of compounds.
- acyclic enones such as methyl vinyl ketone
- cyclic enones such as cyclohexenones and cyclopentenones
- steroidal enones such as 3-oxo-delta-4 steroids
- furanones and butenolides
- natural product enones and Michael acceptors
