Concept explainers
Interpretation:
Theproducts formed from Diels Alder reaction of (2Z,4Z)-hexa-2,4-diene with methyl propenoate are to be determined.
Concept introduction:
A Diels Alder reaction is one between a conjugate diene and a reactant containing a double bond (dienophile) to form a product. The product is called adduct.
Diels Alder reactions are highly stereospecific. The configuration of the dienophile is retained in the product and the reaction is a syn addition reaction.
The dienes react with dienophiles in cis forms rather than trans forms.
Endo and exo refer to the orientation of the dienophile and its electron-withdrawing group when it reacts with a diene in a Diels Ander reaction.
Endo is favored in the transition state of aDiels Ander reaction because it has a lower energy.
