WebbThe Diels-Alder reaction is a powerful synthetic reaction because it joins two separate compounds and forms a cyclic compound that is still highly functionalized. A simple example of one of these reactions is shown in Figure 1. Figure 1: The overall equation. The Diels-Alder reaction is a member of a larger class of pericyclic reactions. These ...
WebbThe Diels–Alder reaction is an electrocyclic reaction, which involves [4+2]‑cycloaddition of 4 π-electrons of the conjugated diene and 2 π-electrons of the dienophile (an alkene or alkyne). The reaction involves the formation of new σ-bonds, which are energetically more stable than the π-bonds.
