7. Propose syntheses for the following compounds, starting with acetylene and any other reagents you might need. OH H. Br

Ph- OC XT :OH₂ Primary amines add to aldehydes and ketones to give imines. Imines are formed in a reversible, acid-catalyzed process that begins with nucleophilic addition of the primary amine to the carbonyl group, followed by transfer of the proton to yield a neutral carbinolamine. Protonation of the hydroxyl group converts it into a good leaving group and an E1-like loss of water yields an iminium ion. Deprotonation yields the product imine and regenerates the acid catalyst. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions NHOH CH3 CH3 NH₂OH OH HN I Ph CH3 OH H₂O CH3 за
