Developing highly active heterogeneous catalysts for the efficient construction of valuable building blocks is of great importance to synthetic chemistry. For this purpose, a mesoporous zeolite ETS‐10 (METS‐10) is synthesized by using a mesoscale silane surfactant as a template and applied to achieve highly efficient syntheses of α,β‐epoxy ketones by employing simple alkenes and aldehydes as starting materials. The high activity of the METS‐10 catalyst is attributed to its unique porous structure and basicity. Electron paramagnetic resonance characterization results and theoretical calculation experimental data reveal that the strong basic sites on METS‐10 catalyst can activate the reaction substrate and intermediate. In addition, the mesopores in METS‐10 catalyst benefit the mass transfer and further improve the catalytic activity.
