1. Provide a synthesis for the shown transformations using only the materials indicated (in the first synthesis carbons can only come from acetylene whereas in all the other syntheses you are free to use whatever source of atoms you see fit). There is no limit to the amount of steps for each synthesis. Br a) HEH Only source of C atoms (can be used as many times as needed) OH - do
6. (18 points total) Synthesis: Devise a synthesis of the following compound from the given starting materials. You may use any other organic or inorganic reagents you deem necessary but you must use the given starting materials as your only source of carbon in the final compound OH several steps OH MeOH HO
Suggest a synthesis of 1, using as starting materials the Her o CO,Et es -CHO 4. a) Lily aldehyde (1) is an ingredient used in perfumery. Suggest a synthesis of 1, using as starting materials, the ester 2 and 1-propanol. You may use any other applicable inorganic and/or organic reagents, but LiAIH, NaOH (aq). PCC, H2, DIBAL, and Pd/C are the most likely choices (depending on your synthetic route). No reaction mechanism(s) is required. Lily aldehyde b) Using 2-methyl-1,3-cyclopentanedione, acetaldehyde...
Starting with nitrobenzene and using any other reagents of your choice, outline a synthesis of para-chloroaniline Using acetic acid as your only source of carbon atoms, show how could you make N-ethylacetamide:
Using only 1-butanol as your source of carbom, provide a
synthesis for the following compound.
Using only 1-butanol as your source of carbon, provide a synthesis for the following compound. You may use multiple equivalents of 1-butanol (use it more than once in the synthesis) Please use reactions that give the desired product as the major product Do not use the acetoacetic ester or malonic ester synthesis Show the product for each reaction step
Using propyne (structure shown) as your only source of carbon atoms, design a synthesis of the target molecule. You may use any organic or inorganic reagents you choose, but all the carbon atoms in the target must have come from propyne originally. Show the product of each step and the reagents needed for each step. Assume you have an unlimited supply of propyne.
