Carboxylic acid is treated with an alcohol and an acid catalyst, an ester is formed and this
reaction is called the Fischer esterification. From the reaction, propose the mechanism of
ester esterification and ester hydrolysis and their relationship
What compounds are obtained from the following hydrolysis reactions?
A variation of the acetamidomalonate synthesis can be used to synthesize threonine. The process involves the following steps:
Ethoxide ion deprotonates diethyl acetamidomalonate, forming enolate anion 1;
Enolate anion 1 makes a nucleophilic attack on acetaldehyde, forming tetrahedral intermediate 2;
Protonation of the oxyanion forms alcohol 3;
Acid hydrolysis yields dicarboxyamino alcohol 4;
Decarboxylation leads to the final amino acid.
Write out the mechanism on a separate sheet of paper, and then draw the structure of enolate anion 1.

- When an α-hydroxy amide is treated with Br2 in aqueous NaOH under Hofmann rearrangement conditions, loss of CO2 occurs and a chain-shortened aldehyde is formed. The mechanism involves the following steps: Base abstracts an acidic amide proton, yielding amide anion 1; The amide anion reacts with bromine in an α-substitution reaction to give N-bromoamide 2. Abstraction of the remaining amide proton by base gives a resonance-stabilized bromoamide anion 3; Rearrangement occurs to yield isocyanate 4; Water adds to the isocyanate to yield carbamic acid 5; Elimination of CO2 yields carbinolamine 6; Following proton transfer, expulsion of ammonia yields the final product aldehyde.
