(a)
To determine: The synthesis of the given compound with the help of an aldol, claisen or another type of condensation.
Interpretation: The given compound with the help of an aldol, claisen or another type of condensation is to be synthesized.
Concept introduction: Aldol condensation is defined as a condensation reaction that involves the nucleophilic addition of an enolate ion to another carbonyl group to form a
(b)
To determine: The synthesis of the given compound with the help of an aldol, claisen or another type of condensation.
Interpretation: The given compound with the help of an aldol, claisen or another type of condensation is to be synthesized.
Concept introduction: In the claisen-ester condensation, nucleophilic acyl substitution takes place on an ester. The enolate ion acts as a nucleophile. It attacks the carbonyl carbon to form a tetrahedral intermediate. Acidity of beta-keto ester products is higher than simple ketones, aldehydes and esters.
(c)
To determine: The synthesis of the given compound with the help of an aldol, claisen or another type of condensation.
Interpretation: The given compound with the help of an aldol, claisen or another type of condensation is to be synthesized.
Concept introduction: Intramolecular aldol reactions of diketones are used for the formation of five and six membered rings. These reactions are known as aldol cyclizations. Aldol cyclization of rings which are larger than six and smaller than five is less common.
(d)
To determine: The synthesis of the given compound with the help of an aldol, claisen or another type of condensation.
Interpretation: The given compound with the help of an aldol, claisen or another type of condensation is to be synthesized.
Concept introduction: Condensation reaction that takes place between two carbonyl group containing molecules involves both nucleophilic addition and alpha substitution. Such a condensation reaction is known as carbonyl condensation reaction. One carbonyl is converted into a nucleophilic enolate ion by a base in this reaction.
(e)
To determine: The synthesis of the given compound with the help of an aldol, claisen or another type of condensation.
Interpretation: The given compound with the help of an aldol, claisen or another type of condensation is to be synthesized.
Concept introduction: Condensation reaction that takes place between two carbonyl group containing molecules involves both nucleophilic addition and alpha substitution. Such a condensation reaction is known as carbonyl condensation reaction. One carbonyl is converted into a nucleophilic enolate ion by a base in this reaction.
