Diels–Alder reaction - Wikipedia

網頁The most common cycloaddition reaction is the [4 π +2 π] cyclization known as the Diels-Alder reaction. In Diels-Alder terminology the two reactants are referred to as the diene and the dienophile . The following diagram shows two examples of [4 π +2 π] cycloaddition, and in the second equation a subsequent light induced [2 π +2 π] cycloaddition. 網頁Which of the following compounds can arise directly from a Diels-Alder reaction? Circle any structures that can. Then, identify the appropriate diene(s) and dienophile(s) that would lead to the compound. Pay attention to E-/Z- stereochemistry in all of the reactants. 網頁4.4.4 Regiochemistry of Diels–Alder Reaction Constitutionally homogeneous cycloadducts are obtained through symmetrically substituted dienes and dienophiles. In contrast, when an unsymmetrical diene and an unsymmetrical dienophile combine in a Diels–Alder reaction, it may afford two constitutionally isomeric cycloadducts. dodge ram pu trucks
