### Retrosynthetic Analysis and Synthesis Planning

**Task:** Perform a retrosynthetic analysis of the following target and devise a synthetic route.

**Structure:**
- **Target Molecule (Left Side):** Resembles a phenyl ring with an attached ketone group (C=O) and an alkene chain.
- **Product Molecule (Right Side):** Resembles a 1,3-diketone with an ethyl ester group (OEt).

**Instructions:**
Consider using the following reagents and methodologies:
- **Protecting Groups:** Utilize protecting groups as necessary in your synthesis.
- **Reagents:**
  - Thionyl chloride (SOCl₂) or phosphorus trichloride (PCl₃)
  - Bromine with sodium hydroxide (Br₂/NaOH)
  - A Gilman reagent (organocopper reagent)
  - Specialized reducing agent: lithium tri-tert-butoxyaluminum hydride (LiAlH(O'tBu)₃)

**Reactions:** 
Incorporate the following reactions where suitable:
- **Alpha-Alkylation:** Introduction of an alkyl group at the position next to a carbonyl group.
- **Haloform Reaction:** A reaction that converts methyl ketones into carboxylic acids or their derivatives.
- **Hydrolysis:** Breaking chemical bonds through the addition of water, often used to convert esters to acids or alcohols.

**Analysis:**
The diagram suggests the transformation of a specific alkene-ketone structure into a more complex esterified diketone. The synthesis requires careful planning of steps to ensure the introduction and protection of functional groups, separation and rearrangement of carbon skeletons, and usage of the correct reagents to achieve the desired transformations. 

Carefully proceed with the synthesis, keeping track of intermediates and the rationale for each transformation step.
