- True or False: Acetylene is a naturally occurring conjugated diene True or False: The Diels-Alder reaction has the stereochemistry of the dienophile is retained in the product. True or False: When looking at kinetic vs. thermodynamic products the kinetic product predominates at low temperature. True or False: the mechanism of the Diels-Alder reaction is three π bonds break; one σ bond and two π bonds form.arrow_forwardFollowing is an example of a type of reaction known as a Diels-Alder reaction 1,3-Pentadiene Ethylene 3-Methylcyclohexene (a racemic mixture) The Diels-Alder reaction between a diene and an alkene is quite remarkable in that it is one of the few ways that chemists have to form two new carbon-carbon bonds in a single reaction. Given what you know about the relative strengths of carbon-carbon sigma and pi bonds, would you predict the Diels-Alder reaction to be exothermic or endothermic? Explain your reasoning.arrow_forwardPredict the products of the following Diels-Alder reactions?arrow_forward
- Which constitutional isomer represents the product of this Diels-Alder reaction?arrow_forwardPredict products of each Diels-Alder reaction (including stereochemistry)arrow_forwardDraw a structural formula for the product of this Diels-Alder reaction, including the stereochemistry of the product.

- Predict the product of the following Diels-Alder reaction. Make sure to indicate stereochemistry whereverapplicable.arrow_forwardWhich of the following statments is TRUE about the Diels-Alder cycloaddition reaction? The best reactions occur with an electron-rich diene and an electron-poor dienophile. The reaction favors the exo-product. Entropy drives the reaction toward the cyclohexene product. The reaction is not stereospecific with respect to the dienophile stereochemistry.arrow_forwardStep 6: Now that you have determined the substrates and mechanism of a Diels-Alder reaction, you will learn how to recognize when you should use the Diels-Alder reaction. In a synthesis reaction, if you are given a cyclohexene product with no other obvious functional group transformations and an electron-withdrawing group two carbons away from the alkene, it is likely made via the Diels-Alder reaction. Deduce the structures of the starting materials to form the Diels-Alder adduct shown. ..... CN CN Diene + Dienophilearrow_forward
- Explain why the Diels Alder reaction would have synthetic significance in the production of biologically active compounds.arrow_forwardA very large number of Diels-Alder reactions are recorded in the chemical literature, many of which involve relatively complicated dienes, dienophiles, or both. Predict the constitution of the Diels-Alder adduct that is expected to form from the combination of diene and dienophile below. Draw the structure of the predicted product, including relevant stereochemistry when applicable. If applicable, use the Bicyclic Stamp tool and guide points to draw each structure.
