Question

How would you selectively go about the following transformations? Can you
accomplish these reactions without protecting groups? Provide a route to perform each transformation and include a brief description of why you chose to do it that way.

The image presents a chemical reaction scheme involving a central compound that undergoes transformations through different reaction pathways labeled A, B, C, and D. Each pathway leads to or originates from structurally similar compounds. Here's a detailed breakdown:

1. **Central Structure**: The main compound consists of a core aromatic ring with an amide linkage. The structure includes hydroxy groups and alkyl chains attached at various positions.

2. **Pathway A**: This reaction pathway leads to a compound with additional hydroxy groups, indicating possible hydroxylation. The configuration suggests the maintenance of the aromatic core with alterations in the side chains or functional groups.

3. **Pathway B**: Leads to a different compound, possibly involving structural rearrangement or removal of certain groups, maintaining the amide group.

4. **Pathway C**: Points towards a compound with slight modifications, like possible oxidation or reduction processes, affecting the side chains or functional groups.

5. **Pathway D**: Shows a reverse reaction route, likely involving deprotection or reformation of the initial central compound from the modified structure shown at the top of the diagram.

This reaction scheme illustrates the chemical transformations and interconversions between a series of related compounds, emphasizing the structural stability of the aromatic core while highlighting changes in functional groups or side chains.
