Exempel på hur man kan använda ENAMINES i en mening

• Akin to enamines, enol ethers are electron-rich alkenes by virtue of the electron-donation from the heteroatom via pi-bonding.
• Silyl enol ethers are neutral, mild nucleophiles (milder than enamines) that react with good electrophiles such as aldehydes (with Lewis acid catalysis) and carbocations.
• Since enamines are generally produced from ketones or aldehydes, this overall process (known as the Stork enamine synthesis) constitutes a selective monoalkylation of a ketone or aldehyde, a process that may be difficult to achieve directly.
• When α-amino alkylphosphonates are employed in olefination, the resulting enamines can be hydrolyzed to ketones.
• Other functional groups that have been reduced with hydrosilanes include amides, and α,β-unsaturated esters enamines, imines, and azides.
• Hydrogenation of imines is complicated by both syn/anti isomerization and tautomerization to enamines, which may be hydrogenated with low enantioselectivity in the presence of a chiral catalyst.
