Ireland-Claisen rearrangement
Introduction
The Ireland-Claisen rearrangement is a chemical reaction of an allylic ester with strong base to give an γ,δ-unsaturated carboxylic acid.[1][2][3][4]
Several reviews have been published.[5][6][7]
Mechanism
Mechanism
The Ireland-Claisen rearrangement is a type of Claisen rearrangement. The mechanism is therefore a concerted [3,3]-sigmatropic rearrangement which according to the Woodward-Hoffmann rules show a concerted, suprafacial, pericyclic reaction pathway.
