Just as there can be intramolecular Aldol condensations, so can there be intramolecular Claisen condensations. These are called Dieckmann condensations. 1) Identify all the a hydrogens in the diester shown. Draw the enolate anion(s) that form when the hydrogen(s) is/are removed. H3CH₂CO OCH₂CH3 2) Draw a mechanism and provide the product(s) formed when the anion(s) attack(s) the other carbonyl carbon in the molecule. All electron movement must be shown with arrows.

QUESTION 12 Consider the following crossed aldol condensation. Which statement explains why a single cross condensation product is formed? 2,2-dimethylcyclohexanone 0 H₂C H₂C H NOCH₂CH₂ ethanol CH₂ CH₂ benzaldehyde O 2.2-Dimethylcyclohexanone has only one alpha carbon which can form an enolate. O Benzaldehyde has no hydrogens attached to the alpha carbon which eliminates the self-condenatation reaction. O 22-Dimethylcyclohexanone is sterically hindered which limits the self-condenstation reaction. All of the above.
