Question: Intramolecular DielsโAlder reactions are possible when a substrate contains both a 1,3-diene and a dienophile, as shown in the following general reaction.
With this in mind, draw the product of each intramolecular DielsโAlder reaction.
a.
b.
Question: Draw the structure of each compound
Question: Draw a stepwise mechanism for the following reaction.
Question: A transannular DielsโAlder reaction is an intramolecular reaction that occurs when the diene and dienophile are contained in one ring, resulting in the formation of a tricyclic ring system. Draw the product formed when the following triene undergoes a transannular DielsโAlder reaction.
