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) 2 (CH3),CHCH Br / Cul/ 4 Li? CHỊCH, CHỊCH 2) H30+ 2. Using any necessary reagents, show how the following synthetic transformations may be achieved. Give reagents and conditions for each step. Include all synthetic intermediates compounds produced during the course of multi-step synthesis). NOTE: You may not use HOC OH 1. For each of the following questions, provide the missing reagents that can be purchased) and conditions or predict the MAJOR product. Indicate stereochemistry and identify a racemic...
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...
