Diels – alder reaction is a [4 + 2] cycloaddition reaction between conjugated diene and dienophile (substituted alkene or alkyne) to form substituted cyclohexene. This reaction occurs in a single step with no intermediates.
A compound with a conjugated double bond in a system is represented as diene.
A substituted alkene or alkyne is represented as dienophile.
Example:
According to stereochemistry,
Cis reactants lead to Cis products and Trans reactants leads to Trans products.
Consider the transition state of the reaction as shown below:
