(a)

Interpretation Introduction

Interpretation:

To describe how the given compound can be prepared using acetoacetic ester synthesis

Concept introduction:

Acetoacetic ester synthesis is a process in which an halide is converted to a methyl ketone with two new carbon atoms (comes from acetoacetic ester).  By use of this method two new alkyl groups can be introduced.  A general scheme of this synthesis is shown below,

Please do remember that if alkyldihalide is used for acetoacetic ester synthesis a cyclic product is expected. (intramolecular acetoacetic ester synthesis)

ORG.CHEM EBOOK W/BBWILEY PLUS>CUSTOM<, Chapter 22.5, Problem 39PTS , additional homework tip  2

Steps involved in acetoacetic ester synthesis are,

  • Deprotonation of α carbon in acetoacetic ester
  • Alkylation of enolate
  • Hydrolysis of ester using aqueous acid
  • Decarboxylation at high temperature
