Propose a synthesis of the cyclic five-membered target molecule shown below using propanal A as you only starting material. You may use any reagents of your choosing, but all of the carbon atoms in the final product MUST come from propanal A. Show all intermediates and reagents for each transformation (do not worry about the solvents). Hint: by counting the number of carbon in the product, we would need three molecules of propanal A.
Choose the reagents suitable for the following transformations.
One of the molecules shown can be made using the Williamson ether synthesis. Identify the ether and draw the starting materials. A B C Strategy: Review the reagents, mechanism and steps of the Williamson ether synthesis. Determine which of the molecules can be made using the steps. Then analyze the two possible disconnection strategies and deduce the starting materials. Identify the superior route. Two possible bonds can be formed to make ether C. The highlighted bond in each structure indicates the bond formed in each route. Let's consider each route and determine which is ideal. O Yo C-option1 C-option2 Consider option 1.
