Draw the orientation and phases of the reacting p-orbitals showing how they overlap in a “suprafacial” geometry to form productWhich compound from the list below can undergo a Diels-Alder reaction?Indicate the reagents (diene and phyllodiene) necessary to obtain the following compound by a Dirls-Alder reaction. H3C H3C CH3 CH3
- Step 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 + DienophileWhen anthracene is added to the reaction of chlorobenzene with concentrated NaOH at 350 °C, an interesting Diels–Alderadduct of formula C20H14 results.
