of nitrosoarenes, olefins, as well as iodonium ylides can be subjected to this reaction to generate the N-aryl isoxazolidines derivatives with moderate to excellent yields. In addition, we demonstrate that this approach employs the 1,3-dipolar cycloaddition of nitrones generated in situ from iodonium ylides and nitroso compounds, with olefins in the absence of any catalysts and additives.

three-component cycloaddition of malonates, nitrosoarenes and alkenes is described. A wide range of isoxazolidines could be obtained in moderate to excellent yields via this method. Mechanistic investigations indicated that the key step in this catalytic system is the straightforward formation of nitrone intermediates through the Cu(OAc)2-catalyzed reaction of malonates with nitrosoarenes.
