WebThe hetero-Diels–Alder reaction is a variant of this reaction and is useful for the synthesis of six-membered heterocyclic rings. In this reaction, either the diene or the dienophile … In organic chemistry, the Diels–Alder reaction is a chemical reaction between a conjugated diene and a substituted alkene, commonly termed the dienophile, to form a substituted cyclohexene derivative. It is the prototypical example of a pericyclic reaction with a concerted mechanism. More specifically, it is … See more The reaction is an example of a concerted pericyclic reaction. It is believed to occur via a single, cyclic transition state, with no intermediates generated during the course of the reaction. As such, the Diels–Alder reaction is … See more The retro-Diels–Alder reaction is used in the industrial production of cyclopentadiene. Cyclopentadiene is a precursor to various norbornenes, which are common monomers. The Diels–Alder reaction is also employed in the production of See more The Diels–Alder reaction was one step in an early preparation of the steroids cortisone and cholesterol. The reaction involved the addition of butadiene to a quinone. See more • Carey, Francis A.; Sundberg, Richard J. (2007). Advanced Organic Chemistry: Part B: Reactions and Synthesis (5th ed.).

WebVideo transcript. - [Narrator] In this video, we're going to look at the stereochemistry of the dienophile. But first, a quick review of the Diels-Alder Reaction. On the left we have our diene; on the right is our dienophile. We know that our Diels-Alder Reaction involves a concerted movement of six pi electrons. hippo flooring
