After formation, the enamine adds to the electrophilic alkene carbon of the a α, … WebEnamines act as nucleophiles in a fashion similar to enolates. Because of this enamines can be used as synthetic equivalents as enolates in many reactions. This process requires a three steps: 1) Formation of the enamine, 2) Reaction with an eletrophile to form an iminium salt, 3) Hydrolysis of the iminium salt to reform the aldehyde or ketone.

WebAs with silyl and alkyl enol ethers, enamines react with boron hydrides to afford the corresponding simple alkenic products. In the case of cyclohexyl enamine, hydroboration gives the β-amino organoborane, which upon acid-induced anti elimination affords cyclohexene as the product. 96 Similar conditions were employed by Friary et al. 91 in …
