8. Alcohols are readily available synthetic starting materials. Propose a series of reactions to achieve the following syntheses starting from alcohols. Clearly show the reagents used for each step and the synthetic intermediates. a. For this synthesis, use the given starting alcohols and any inorganic reagents needed. You may use the two alcohols in separate reactions as needed. M OH + OH ... i
Provide a series of synthetic steps to induce the following conversion: Ethanol must be used as your carbon source. If you wish to use acetylide show how it would be made from ethanol. The same requirement stands for a Grignard reagent. CH3 H2C OH H2C CH3
Problem IV. Synthesis (24 points). These transformations will require multiple steps. Provide the reagents for each step and draw out your proposed synthetic intermediates. Please do not draw curved arrows; this prob- lem is not asking for mechanisms. You do not need to provide solvents for the reactions. (1) (12 points) Provide a synthetic route-i.e., a sequence of reactions-to produce compound SS from compound RR using any other starting materials and reagents you wish. RR (2) (12 points) Provide a...
