Witryna13 lis 2024 · 8. Summary: Stereochemistry of the Diels-Alder Reaction. The stereochemistry of the dienophile is preserved in the Diels-Alder product. The “outside” groups on the diene end up on the same face of the new six-membered ring, as do the “inside” groups. When both the diene and dienophile are substituted, diastereomers … WitrynaThe Diels-Alder reaction is enormously useful for synthetic organic chemists, not only because ring-forming reactions are useful in general but also because in many cases …

This Diels-Alder reaction without worrying about stereochemistry. So we know that a Diels-Alder reaction, involves a concerted movement of six pi electrons. So if these pi electrons move into here before a bond between these two carbons, these pi electrons move into here.
