- Draw the products of the following Diels-Alder reactions, and indicate the stereochemistry at all stereogenic centers.Rank the following radicals from least to most stable.Indane can undergo free-radical chlorination at any of the alkyl positions onthe aliphatic ring.(a) Draw the possible monochlorinated products from this reaction
- In 4+2 cycloaddition, ENDO stereochemistry is preferred because: endo stereochemistry allows the diene to adopt s-cis conformation. endo stereochemistry results in less steric hindrance. the transition state leading to endo stereochemistry is higher energy. it allows for additional π to π overlap between the diene and the dienophile.Diels-Alder reaction What is the relative stereochemistry of the major bicyclic adduct, endo or exo?Draw the products of each Diels–Alder reaction, and indicate the stereochemistry.
