The Diels–Alder reaction between isoprene and methyl acrylate over several zeolites was thoroughly investigated. ZSM‐5 zeolites provided the highest productivity in methyl 4‐methylcyclohex‐3‐enecarboxylate isomer, achieving 0.219 mmol product per mmol H + in 1 hour. In addition, this study highlights the influence of ZSM‐5 zeolite’s Brønsted acidity and crystal size on its performance in the Diels–Alder reaction. An optimal configuration between the two reactants within the medium‐pore‐sized ZSM‐5 framework is obtained, thus suggesting the presence of a confinement effect.
