Iwanow Reaction (Ivanov Reaction)

Ivanov Reagents are carboxylate enolates (enediolates, or carboxylic acid dianions) derived from phenyl acetic acid or substituted analogs, and react with aldehydes to give β-hydroxy acids, similar to the Aldol Addition.

The stereoselectivity can be explained with the Zimmerman-Traxler Model, which predicts a six-membered cyclic transition state leading to excellent stereoselectivity for anti-substituted products.
