Question
Chapter 23.12, Problem 11P
Interpretation Introduction
Interpretation:
The product obtained in the Claisen rearrangement of
Concept introduction:
Allyl phenyl ethers undergo Claisen rearrangement to form
In this type of rearrangement, the allyl group migrates from the oxygen atom in the ring to the carbon atom which is at an ortho position to it.
The transition state formed in the first step of the Claisen rearrangement is similar to that in the Diels-Alder cycloaddition.
