Abstract: A series of 1-aza-2, 8-dioxabicyclo[3.3.0] octanes containing multiple functional groups weresynthesized though [3+2] cycloaddition reaction of 4-substituted phenyl-3, 5-bis (methoxycarbonyl)-2-isooxazoline-N-oxides with ethyl acrylate as dipolarphile.The reaction underwent under a mild conditionand offered the products with higher yields (50%-93%).The structures of the compounds synthesizedwere confirmed by elemental analyses, 1H NMR, 13C NMR, IR and MS.

Key words: 2-Isooxazoline-N-oxide, 1-Aza-2,8-dioxabicyclo[3.3.0] octane, [3+2] Cycloaddition
