Propose mechanisms for the following reactions.

Short Answer

Expert verified

Mechanism followed as:

Step by step solution

01

Aldol self-condensation

It is the reaction of the enolate ion with another carbonyl group lead to the form α,β unsaturated aldehyde or ketone.

02

Formation of the product

As the hydrogen is protonated from the reacting species formation of enolate ion occurs which combines with another group of carbonyl followed by the removal ofOH- formation ofα,β unsaturated aldehyde occur.

03

Mechanism

The mechanism as follow:

A student wanted to dry some diacetone alcohol and allowed it to stand over anhydrous potassium carbonate for a week. At the end of the week, the sample was found to contain nearly pure acetone. Propose a mechanism for the reaction that took place.

When cyclodecane-1,6-dione is treated with sodium carbonate, the product gives a UV spectrum similar to that of 1-acetyl-2-methylcyclopentene. Propose a structure for the product, and give a mechanism for its formation.

(A true story.) Chemistry lab students added an excess of ethyl magnesiumbromide to methyl furoate, expecting the Grignard reagent to add twice and form the tertiary alcohol. After water workup, they found that the product was a mixture of two compounds. One was the expected product having two ethyl groups, but the unexpected product had added three ethyl groups. Propose a mechanism to explain the formation of the unexpected product.

Question:Show how you would use an aldol, Claisen, or another type of condensation to make each compound

e.

A reaction involved in the metabolism of sugars is the splitting of fructose-1,6-diphosphate to give glyceraldehyde3-phosphate and dihydroxyacetone phosphate. In the living system, this retro-aldol is catalyzed by an enzyme called aldolase; however, it can also be catalyzed by a mild base. Propose a mechanism for the base-catalyzed reaction
