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:

Be sure to answer all parts. In theory, the intramolecular aldol reaction of 6-oxoheptanal could yield the three compounds shown below. It turns out, though, that l-acetylcyclopentene is by far the major product. Why are the other two compounds (B and C) formed in only minor amounts? Select the single best stepwise mechanism to show how each of the three products is formed. CHO OH CHO HAO 6-oxoheptanal 1-acetylcyclopentene major product l-acetylcyclopentene is the major product formed because its enolate...
3. Draw all the aldol addition products that are formed when a
mixture of acetaldehyde and pentanal is treated with aqueous sodium
hydroxide.
4. A reaction, such as described in question 3, which produces a
mixture of products is generally not useful for organic synthesis.
Suggest a change in the reaction starting materials for question 3
that would produce a single, similar product.
5. Draw a generic mechanism for aldol condensation.
6. The last step for an aldol condensation involves...
7. Draw all monochloro derivatives that might be formed when the
following molecule is allowed to react with Cl2 under UV
irradiation (light). For each structure, indicate, with an
asterisk, any stereocenters (chiral centers) that might be present.
(Hint: 7 products)
8. What is the major organic product obtained from the following
reactions?
