Question

Choose the correct products for the following Diels-Alder reactions.

Answer 1

Solution :-

For the reaction A the product is the structure shown in the option ‘d’ last option.

Because the dienophile is having trans geometry therefore it gives the addition of the groups of the dienophile on the opposite sides.

For the reaction B The product is the structure shown in the option ‘a’ (first option )

Because the dienophile is the cis therefore COOH and CN groups lies on the same side

For the reaction ‘C’ the product is the structure shown in the option ‘d’ because both the diene and dienophile having trans orientation.

For the reaction ‘D’ the product is the structure shown in the ‘d’ because it gives the endo addition product.

For the reaction ‘E’ the product is the structure shown in the option ‘c’

Following image shows the correct product marked for each reaction.
