Sir,Please explain the INTRAMOLECULAR ALDOL CONDENSATION in detail with mechanism.

Dear vikas

The reaction involves an enolate reacting with another molecule of the aldehyde

few important thing regarding the adol reaction

It is a  Nucleophilic addition Reaction

Reagents : commonly a base such as NaOH or KOH is added to the aldehyde.

The reaction involves an enolate reacting with another molecule of the aldehyde.

Remember enolates are good nucleophiles and carbonyl C are electrophiles.

The products of these reactions are b-hydroxyaldehydes or aldehyde-alcohols = aldols.

The simplest aldol reaction is the condensation of ethanal. This is shown below in 2 different representations (the line diagrams are less cluttered)

Mechanism
