1. Suggest a reasonable mechanism for the following reaction. na za i.EtON, EtOH, 25°C ii. H30 Answer: 2. There are several possible cyclization products that might be formed when 5-methyl-6-oxoheptanal undergoes intramolecular aldol condensation in presence of ethoxide. Draw the structures of all these possible products. Comment on which of these is likely to be the major product, clearly explaining your rationale Answer:
1. Consider the following molecule (12 marks total) i. Provide the reaction conditions, and major product, for the monobromination of this molecule (2 marks) ii. Provide the full arrow pushing mechanism for the formation of the major product (making sure to include all initiation, and propagation steps as well as one termination step) (4 marks) (Continuation of Question 1) iii. Provide an explanation for why only one product is obtained through monobromination of this molecule (2 marks) iv. When reacting...
Consider the following reaction NaOEt ------>EtOH a) Identify the mechanism(s) by which the reaction will occur. If there is more than one mechanism that can operate, identify the mechanism that will predominate. Explain your reasoning clearly. b) Predict all possible product(s) that will be formed and identify them as major and minor products.
Show the complete detailed mechanism for the following reaction. Provide all possible products and indicate specific stereochemistry or regio-chemistry if appropriate Cl B. NaOH. H,O → 2 350°C products
13. Briefly explain why the following hypothetical reaction is unlikely to occur. (4 pts) на I is a terpene found in cinnamon, sassafras, and orange flower oils. A possible retrosynthesis step for linalool is shown, starting with an octene carbonyl.Show a forward synthetic route here using this octene carbonyl and ethyne (CHa) as a source of the two additional carbons. If your synthesis involves a step that makes multiple products, show them all and assume that you have the ability...
I don't know how to distinguish E1 and E2 reacions. For E2 reactions I have trouble with the transition state. These reactions need intermediate steps and transition states but not products. 1. (i) (2.5 points x 10-25 points) For the following elimination reactions Write bond-line structure of the substrate and the reagent Write full mechanism for the reaction transition state for E2, intermediate for El) and name the reaction either as El or E2; Write all possible products of the...
