Chapter 21, Problem 21.91P

Interpretation Introduction

Interpretation:

Synthesis of $\text{3-oxo-2-methylpentanal}$ is to be shown. Any inorganic reagent may be used here, but carbon source must be alcohols containing three or fewer carbons.

Concept introduction:

$\text{3-oxo-2-methylpentanal}$ has six atoms; therefore, one reaction alters the carbon skeleton owing to the limitation of a three –carbon atom starting material. The product is a $\text{1, 3-dicarbonyl}$ compound, which suggests that a crossed condensation reaction could have occurred.
