- n. any metal salt of the enol form of a tautomeric aldehyde or ketone
Sorry, no etymologies found.
It exploits the promiscuous aldolase activity of the enzyme macrophomate synthase (MPS) to add pyruvate enolate diastereoselectively to a wide range of structurally complex aldehydes.
(The mixture gradually became homogeneous as the precipitated Na-enolate salt of the di-Me-acetonedicarboxylate re-dissolved with heating).
This structure has a resonance form, an enolate ion, in which a double bond is formed between this negative carbon and the carbonyl carbon, the C-O bond becomes a single bond, and the negative charge is placed on the oxygen atom.
Protonation of the carbonyl oxygen favors formation of the enolate
Aldol condensation reactions occur when the carbanion carbon of an enolate reacts with the carbonyl carbon of a ketone or aldehyde, forming a new carbon-carbon bond.
