Esters are formed by the reaction of alcohol and carboxylic acid in the presence of a sulphuric acid as a catalyst. The reaction is known as esterification.
The amino group of glycine methyl ester hydrochloride reacts with the double bond of acrylonitrile, it occurs the Michael reaction, then generates CNCH2CH2NHCH2CO2Me.
The nucleophilic oxygen in the alcohol can attack the carbonyl carbon of the aldehyde to form an ester. This reaction can be carried out under acidic conditions.
The reaction between a carboxlic acid and an alcohol is named as esterfication. Ester is formed during this reaction.
The by-product is water.

Reformatsky reaction The Reformatsky reaction(sometimes spelled Reformatskii reaction) is an organic reaction which condenses aldehydes 1 (or ketones) with α-halo esters 2 with metallic zinc to form β-hydroxy-esters 3.It was discovered by Sergei Nikolaevich Reformatskii. The organozinc reagent, also called a 'Reformatskii enolate', is prepared by treating an alpha-halo ester with zinc dust. Reformatskii enolates are less reactive than Grignard reagents and hence nucleophillic addition to the ester group does not occur.

The parent carboxylic acid and the parent alcohol can be obtained by hydrolysis of an ester. Hydrolysis is a reaction in which a molecule is split up by the chemical action of water. The breakdown of an ester is an example of hydrolysis because water is used to separate the ester into alcohol and a carboxylic acid.
The nucleophilic oxygen in the alcohol can attack the carbonyl carbon of the aldehyde to form an ester. This reaction can be carried out under acidic conditions.

Acid has little or no effect except possible exchange of acid groupd between ester and the introduced acid - transesterification. Base - a salt of the acid part of the ester will form and the alcohol or some substituted form of it - that depends on the base used. There is no simple answer as the acids and bases that could be used are almost limitless.
