4. Design a synthesis for the following molecule. You may only use carbon containing reagents if they are in the list on the right. You may use any other non-carbon containing reagents that you would like. Target molecule: Carbon containing molecules that you may use (you don't have to use all of them): -Br Out NaCN Br CO2
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.
Design an efficient synthesis for the following target molecule, using any hydrocarbons with three or less carbon atoms as starting materials to build the target molecule; also using any solvents or reagents that do not contribute carbon atoms to the final structure. SHOW YOUR ANSWER AS A STEPWISE REACTION SCHEME SHOWING THE REAGENT REQUIRED AND PRODUCT OF EACH STEP DO NOT SHOW MECHANISMS (i.e. curly arrows are NOT required) Any solvents or reagents that do not contribute carbon atoms to...
b. For this synthesis, start with alcohols containing three or fewer carbon atoms. You may use any needed inorganic reagents, but all of the carbon atoms in your product must come from the starting alcohols. Alcohols containing three or fewer carbon atoms each
Provide a step-wise synthesis of the molecule shown below using
the two starting materials provided and anything else you may
need.
5. Provide a stepwise synthesis of the molecule shown below using the two starting materials provided and anything else you may need. a. anything plus any other molecule containing 1 C plus any other reagents necessary. cl Hint: this is a highly convergent synthesis. You will need to prepare two separate molecules, then birng them together to form the...
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.

stepwise synthesis for N-propylbutanamide using 1-propanol and/or
carbon dioxide as your only source of carbon
Use Using the reagents below, list in order (by letter, no period) those necessary to provide this synthesis. Note: Not all spaces provided may be needed. Hints: First receive a Grignard reagent in steps 1 and 2. Use propanol in step 5. In step 9 a product from step 4 reacts with a product from step 8. a. NH3 b. Mg/ether c. SOCl2 d. 1....
12. Propose a reasonable synthesis for the following molecule. You must use the given starting materials and any reagents we have studied in our course. There are several possible approaches. (30 pts) Br Given: NaCN CH4 CO2
Problem 3 Propose a synthesis of the following molecule from the given starting material. You may use any reactions we have learned in this course so far, and any reagents containing the carbon atoms you need. If you make a mixture in any of the steps, place a box around the compound you would separate from the mixture, and carry on with your synthesis assuming you can isolate the desired regioisomer. NH2
3. Design a synthesis of the following molecule starting from
benzene and molecules of two or less carbon atoms. You are not
limited in your choice of reagents or number of steps.
