Difference between claisen schmdit reaction and aldol condensation?

∙ 10y ago
Aldol condensation is the reaction of two aldehydes in the presence of a basic catalyst. The aldol condensation leads to an aldol product, in which an hydroxyl group is attached to the beta carbon of an aldehyde.
Claisen condensation is similar to aldol condensation, but is involves two esters instead of two aldehydes. The product of a Claisen condensation is a beta-keto-ester, a compound characterized by an ester with its alpha carbon being a ketone.

The Claisen-Schmidt reaction involves the condensation of two carbonyl compounds, typically an aldehyde and a ketone, to form an α,β-unsaturated carbonyl compound. In contrast, aldol condensation involves the condensation of an aldehyde or ketone with itself to form a β-hydroxy carbonyl compound. The key difference is the presence of two different carbonyl compounds in the Claisen-Schmidt reaction, while aldol condensation involves one carbonyl compound reacting with itself.

Is claisen condensation a condensation reaction?
Of course,The Claisen Condensation is typically the reaction between two esters, in the presence of base, leading to formation of an ester enolate that reacts with an uncharged ester, thereby displacing it's "alcohol part" as the leaving group. The sequence leads to the formation of beta ketoesters. The intramolecular (cyclic) version of the Claisen Condensation is known as the Dieckmann Condensation, and is illustrated through the article, "Dieckmann Condensation Missing Piece."
What condensation reaction occurs in the body?
Two of the most important from an academic standpoint are the Aldol addition which involves combining aldehyde, ketones or N,N-disubstituted esters to form more complex molecues. In the case of a biological system single collagen proteins are linked to form cross- linked collagen via an aldol addition of 2 aldehyde molecules, as well as the claisen condensation which is best known for the reaction between 2 thioesters acetyl thioester and malonyl thioester to form part of a fatty acid used in protein synthesis.

Can propanedial be easily prepared by a simple Claisen condensation?
Not really because aldol condensation of 2 CH3CHO would be a major competing process.
Which of the starting materials should be present in excess why what side reaction will compete if the reagents are present in comparable amounts?
(CH3)2CHCOOCH3 should be present in excess because it does not form a stable product from Claisen condensation with itself and it will be able to preferentially react with enolate ions from the first ester. Side reaction ( Condensation of first ester with itself) :- 2 CH3CH2CO2CH3 - > CH3CH2OCO2CH2CH3 + CH3CO2CH2CH3
