5. (8 points) Devise a synthesis to the following target using both of the organic precursors from the chemical bank and any transformation we have learned in organic I and II. Target: Chemical Bank: CI он CI O O2N NO2 5. (8 points) Devise a synthesis to the following target using both of the organic precursors from the chemical bank and any transformation we have learned in organic I and II. Target: Chemical Bank: CI он CI O O2N NO2
7. (6 points) Devise a synthesis to the amino acid threonine using the organic precursors from the chemical bank and any transformation we have learned in organic I and II. You will not use all of the compounds in the chemical bank. Target Chemical Bank: NaCN NH BrMg
9. Devise a synthesis of the following compound using the given lactone. You may also use any needed inorganic or organic reagents but all of the carbons in the target molecule must come from the given starting materials.
9. Devise a synthesis of the following compound using the given lactone. You may also use any needed inorganic or organic reagents but all of the carbons in the target molecule must come from the given starting materials.
Devise a synthesis of the following compound using the given compounds (you may use each one more than once if needed). You may also use any needed inorganic or organic reagents but all of the carbons in the target molecule must come from the given starting materials.
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
Please answer question 4 with a full explanation. 4. (9 points) Multi-step synthesis. Devise a synthesis for the target molecule starting from benzene and small alcohols with no more than two carbons. You can use any inorganic reagents necessary target 5. (10 points) Analysis of 'H NMR spectrum. Below is the 'H NMR spectrum of the product from this week's experiment.
3) Devise a synthesis of the following compound using the given compounds (you may use each one more than once if needed). You may also use any needed inorganic or organic reagents but all of the carbons in the target molecule must come from the given starting materials. Hint: this synthesis will require you to use ozonolysis and a reaction that starts with the letter DI
2) Devise a synthesis of the following compound using only ethanol. You may also use any needed Inorganic or organic reagents but all of the carbons in the target molecule must come from ethanol. Hint: this synthesis will require you to use a Claisen reaction
Synthesis using Carbonyla-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. My two target molecules are number 2 and number 12 in the last page. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the...
