Interpretation Introduction

Interpretation: The mechanism for the given Carroll rearrangement reaction is to be drawn.

Concept introduction: Carroll rearrangement is a reaction in which β−keto ester reacts with allylic alcohol in the presence of base to give unsaturated carbonyl compound.

In the sigmatropic rearrangement, the rearrangement of pi bond and the breaking of sigma bond take place. This results in the generation of new sigma bond in the product. In this type of rearrangement, the number of pi bonds remains constant in the reactant as well as in the product.
