Assuming that you have available only alcohols or esters containing no more than four carbon atoms, complete the synthesis of the following compound. Begin by completing the retrosynthetic analysis. You must use a Grignard reagent at one step in the synthesis. If needed, you may use oxirane and you may use bromobenzene, but you must show the synthesis of any other required organic compounds. Assume you have available any solvents and any inorganic compounds, including oxidizing and reducing agents, that you require. (a) Rerrosynthetic Anatywis Synthesis B Structure of A
