Thermaldecomposition of 3-(azidomethylene)dihydrofuran-2-one in various solvents at temperatures above 70°C gave a spiroaziridine derivative with an excellent diastereoselectivity. A mechanism of this new kind of substituted vinylazidedecomposition has been suggested based mainly on the stereochemistry and kinetic data of the reaction. A spiroazirine derivative proposed as a reaction intermediate
