9.60 (••9) Retrosynthetic analysis is the process of working backwards to develop the synthesis of a new compound. In chapter 10, we will begin developing multi-step syntheses in this manner. For now, try to work backward a single step by suggesting an alkene and a reagent that would give the product shown. product (a) (c) Ph (e) O OH он (h) CH3 " "to
