Step by step solution

01

Diels-Alder reaction

The Diels-Alder reaction occurs between a conjugated diene and an alkene called the dienophile.

The diene in a Diels-Alder reaction will be electron-rich, whereas the diene must be electron-poor alkenes and alkynes.

02

Example of Diels-Alder reaction

An example of Diels-Alder reaction is shown:

Example for Diels-Alder reaction

03

To find the product and stereochemistry

A cis dienophile will always form cis-substituted cyclohexene, and a trans dienophile will always form trans-substituted cyclohexene.

Representation of product of A

Here the dienophile is in cis position, combining with a diene to form a cis-substituted product.

Question: Draw the products of the following Diels鈥揂lder reactions. Indicate stereochemistry where appropriate.

a.

d.

Question: Diels鈥揂lder reaction of a monosubstituteddiene (such as CH2=CH-CH=CHOCH3) with a monosubstituteddienophile (such as CH2=CHCHO) gives a mixture of products, but the 1,2-disubstituted product often predominates. Draw the resonance hybrid for each reactant and use the charge distribution of the hybrids to explain why the 1,2-disubstituted product is the major product.

Question: What diene and dienophile are needed to prepare each product?

a.

b.

c.

Question: Draw the structure of each compound

  1. (Z)-penta-1,3-diene in the s-trans conformation
  2. (2E,4Z)-1-bromo-3-methylhexa-2,4-diene
  3. (2E,4E,6E)-octa-2,4,6-triene
  4. (2E,4E)-3-methylhexa-2,4-diene in the s-cis conformation

Question: Label each product in the following reaction as a 1,2-product or 1,4-product, and decide which is the kinetic product and which is the thermodynamic product.
