Question
Fill in the missing structure(s) for the reaction pathways shown below. Provide all
starting material(s), reagent(s), or product(s). If more than one product can be formed,
draw all major products. If more than one starting material or reagent is possible, write
all starting materials and reagents.
Transcribed Image Text:The image contains four chemical reactions labeled h, i, j, and k, each with a starting compound, reaction conditions, and a product.
**Reaction h:**
- Starting compound: A ketone with the structure C6H5-C(O)-C(CO2CH3)-CH3.
- Reaction steps:
1. Sodium methoxide (NaOCH3)
2. Ethyl chloride (CH3CH2Cl)
3. Sodium methoxide (NaOCH3) again
4. Methyl bromide (CH3Br)
5. Sodium hydroxide (NaOH)
6. Acid and heat (H+, Δ)
- The product is not shown and is represented by an empty box.
**Reaction i:**
- Starting compound: Phenylpropanoic acid ethyl ester.
- Reaction conditions not specified (empty box).
- The product is a compound with phenyl groups and an ester linkage.
**Reaction j:**
- Starting compound: A β-keto ester with the structure C6H5C(O)CH2C(O)CH3.
- Reaction conditions not specified (empty box).
- The product is a cyclic ketone.
**Reaction k:**
- Starting compound: A diketone with phenyl groups.
- Reaction steps:
1. Sodium methoxide (NaOCH3)
2. Acetaldehyde (CH3CHO)
3. Acid (H+)
- The product is not shown and is represented by an empty box.
Each reaction involves a series of organic transformations that likely include nucleophilic substitutions, condensations, and cyclizations.
