Conjugated enones zinc dienolates

In this section, reactions of zinc dienolates with carbonyl compounds, imines and conjugated enones will be considered all of these reactions have been proved to be reversible, and, hence, conditions favouring either kinetic or thermodynamic control will drive the reaction towards the formation of different regioisomers. Generally, equilibrating conditions lead to attack at the position of 190, as a thermodynamically more stable conjugated carbonyl or carboxylic compound is formed on the other hand, kinetic control leads to attack at the electron richer a-position.
