Step-by-step solution

Detect the diene and dienophile

Find the 1,3-diene and the dienophile in the given reactions. Place the diene on the left and the dienophile on the right side.

Cleavage of bonds

The three double bonds of the 1,3-conjugated diene and the dienophile cleave to form new bonds such that a ring is formed.

Products of the given reactions

a. The dienophile is re-drawn such that the double bond is right in front of the conjugated diene. The double bonds are broken to form a ring.

Products of a

b. The structures are re-drawn, and the bonds are cleaved to form a ring.

Products of b

c. The structures are re-drawn, and the bonds are cleaved to form a ring.

Product of c

d. The structures are re-drawn, and the bonds are cleaved to form a ring.
