Show the product of reaction of the indicated ester with LDA, followed by butyl iodide.

 

tho CH,CH3 1. Provide a correct name for the indicated ester. 2. How many signals would we expect to see in the BC NMR spectrum? 3. Show the combination of reagents required to synthesize the indicated structure using a Fischer esterification reaction. 4. a. The indicated ester is submitted to Claisen condensation conditions, using the appropriate alkoxide base and a second acidification step. The product of this reaction has molecular formula C19H2803. Draw the structure of this product. b. The C19H2803 product produced in (4a) is then taken through the saponification, acidification, decarboxylation sequence to produce a ketone with molecular formula C1,H220. Give the name of the final ketone product.
