The Diels–Alder reaction is most useful for synthesizing molecules in the lab. But scientists believe that specific enzymes catalyze Diels–Alder reactions in some organisms. Examples are the formation of lovastatin, a cholesterol-lowering drug found in oyster mushrooms, and Spinosyn A, a natural insecticide produced by a certain bacterium. Comment.

Asymmetric Diels–Alder. Substrates with bulky substituents will affect the diastereoselectivity of a Diels–Alder reaction by limiting the approach of the diene/dienophile pair. Here, we see the preferred endo product that minimizes steric interactions with the phenyl substituent (Synthesis 2002, 2457-2463).

At 25°C the isomer produced is the endo product, however at 90°C the exo isomer predominates. Additional studies have shown that at 90°C the equilibrium between the endo and exo products favors the exo isomer. O. a) Draw each isomeric product, endo and exo.
