Concept introduction:
To give:
The enone product expected from the aldol condensation of cyclopentanone.
b)
Interpretation:
The enone product expected from the aldol condensation of acetophenone is to be given.
Concept introduction:
Aldehydes and ketones with α-hydrogen undergo a base catalyzed carbonyl condensation reaction in aldol condensation. In this reaction two molecules of the reactant combine by forming a bond between α-carbon of one molecule and the carbonyl carbon of the second molecule. The product obtained, a β-hydroxyaldehyde or ketone upon heating eliminate a molecule of water to yield the enones, α,β-unsaturated aldehydes or ketones.
To give:
The enone product expected from the aldol condensation of acetophenone.
c)
Interpretation:
The enone product expected from the aldol condensation of 2-methylbutanal is to be given.

- What aldol product is formed when two molecules of butanal react together in the presence of base? What reagents are needed to convert this product to each of the attached compounds?arrow_forwardIn theory, the intramolecular aldol reaction of 6-oxoheptanal could yield the three compounds shown. It turns out, though, that 1-acetylcyclopentene is by far the major product. Why are the other two compounds formed in only minor amounts? Draw a stepwise mechanism to show how all three products are formed.arrow_forwardWhat aldol product is formed when two molecules of butanal react together in the presence of base?
