Abstract 3-Alkoxy-2H-azirines 4 have been prepared by treatment of enol ethers 6 with iodine azide followed by base-catalysed elimination of HI and thermolysis of the resulting vinyl azide 5. Azirines 4 readily undergo electrophilic additions, to yield products resulting from cleavage of either the N (1)-C (3) or the N (1)-C (2) bond. Reaction of 4 with trimethylsilyl cyanide yields highly functionalized aziridines 12. Thermolysis of 4 produces ...
