Abstract: Two oxa macrocyclic compounds were synthesized via double [2+2] photocycloaddition reaction between 6,6′-dimethyl-4,4′-(trimethylenedioxy)-di-2-pyrone and ethylene glycol dimethacrylates(n=1~3) by photosensitizing effect of benzophenone in acetonitrile solution with yields of 14% and 7%, 20% and 11%, 31% and 14%, respectively. The structures of products were identified by FTIR, 1H NMR, MS and elemental analysis. The synthetic method has several advantages such as mild reaction conditions, simple operation and environmental friendliness.

Key words: di-pyrone, ethylene glycol dimethacrylate, cycloaddition, photsynthesis
