Chapter 29, Problem 44P

Interpretation Introduction

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

Concept introduction: In biological reactions, allylic carbocations are the intermediates that are required for the formation of Farnesyl diphosphate.

The general steps involved in the biological formation of Farnesyl diphosphate are stated below.

➢ The first step is the generation of allylic carbocation by the loss of the diphosphate group.

➢ The second step is the nucleophilic attack of isopentyl diphosphate to form new bond.

➢ The third step is the deprotonation to give final product.
