Question:

Consider a process that attempts to prepare tyrosine using a Hell‑Volhard‑Zelinski reaction:

(a) Identify the necessary starting carboxylic acid.

(b) When treated with Br₂, the starting carboxylic acid can react with two equivalents to produce a compound with molecular formula C₉H₈Br₂O₃ , in which neither of the bromine atoms is located at the a position. Identify the likely structure of this product.
