Chapter 17, Problem 17.33P

Interpretation Introduction

(a)

Interpretation:

How the given compound can be synthesized from $\text{hex-4-en-3-one}$ is to be shown.

Concept introduction:

Organometallic compounds are very useful compounds in organic synthesis. One of them is lithium dialkyl (or diaryl) cuprate (${\text{R}}_2\text{CuLi}$). The reagent, often simplified as the nucleophile ${\text{R}}^{-}$, adds to $\text{α,β-}$ unsaturated ketones in reversible manner, giving a $\text{1, 4-}$ addition product.
