Design a multi-step synthesis for each of the following target molecules from the indicated starting material. Show the reagents needed for each step and the product of each step. Do not show any mechanisms. Draw the structures of the diene and the dienophile that reacted to form the Diels-Alder product shown. Provide the missing reagents in this multistep synthesis.
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
Design a synthesis for the following molecule starting from
commercially available starting materials. You may use any reagents
along the way that are commercially available. Should a subtrate
you need not be commercially available, then you need to show me
how you would synthesize it.
Pay
close attention that your design takes into account the
stereochemistry.
