For the given Diels-Alder reaction, the product formed should be determined. Concept introduction: Cycloaddition reaction is a concerted addition reaction of two reactants to form a ring; in which two π-bonds are converted to two σ-bonds . Diels-Alder reaction is a [ 4+2 ] cycloaddition reaction, in which a π-system having four atoms (diene) and a π-system having two atoms (dienophile) are undergoing in cycloaddition reaction and producing a substituted cyclohexene . The mechanism of the ring formation in the Diels-Alder reaction is drawn by using three arrows representing the shifting of π-bonds in the two π-systems in a clockwise or counter clockwise fashion, so that the ring formation will take place. If the dienophile is a trans- alkene , then the product will be trans-product. To determine: the product formed for the given Diels-Alder reaction.

Question

Chapter 16.7, Problem 3LTS

Interpretation Introduction

Interpretation:

For the given Diels-Alder reaction, the product formed should be determined.

Concept introduction:

Cycloaddition reaction is a concerted addition reaction of two reactants to form a ring; in which two π-bonds are converted to two σ-bonds.

Diels-Alder reaction is a [4+2] cycloaddition reaction, in which a π-system having four atoms (diene) and a π-system having two atoms (dienophile) are undergoing in cycloaddition reaction and producing a substituted cyclohexene.

The mechanism of the ring formation in the Diels-Alder reaction is drawn by using three arrows representing the shifting of π-bonds in the two π-systems in a clockwise or counter clockwise fashion, so that the ring formation will take place.

If the dienophile is a trans-alkene, then the product will be trans-product.

To determine: the product formed for the given Diels-Alder reaction.
