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.
