Question

This is an organic chemistry question regarding the Diels-Alder reaction. The problems are 16.22 and 16.18. I would like to know if I did these correctly. If I did not, could someone help me go through the process?

Several rules govern the course of the Diels-Alder reaction eaction to Both ends of the con jugated diene must be close to the π bond of the dienophile for r occur. Thus, an acyclic diene in the s-trans conformation must rotate about the central C-ca bond to form the s-cis conformation before reaction can take place s rotate rotate s-trans strans reactig s-cis reacting conformation s-trans s-cis reacting conformation This rotation is prevented in cyclic dienes. As a result: double bonds are constrained in the s-cis conformation, the diene is unusually When the two reactive When the two unreactive When the two double bonds are constrained in the s-trans conformation, the diene is an s-cis 1,3-diene→ very reactive an s-trans 1.3-diene unreactive diene Problem 16.19 Rank the following dier
