3,4-Bis(ethoxycarbonyl)-1,2,5-oxadiazole 2-oxide (1) has been shown to react with several olefins in a molar ratio of 1:2, giving 5-(ethoxycarbonyl)-1-aza-2,8-dioxabicyclooctanes (2).Evidence is presented that these products arise from 1,3-dipolar cycloaddition, elimination of ethyl cyanoformate from the initial cycloadducts, and 1,3-dipolar cycloaddition of the resulting isoxazoline N-oxides with another mole of olefin.
