A general and efficient three-component protocol for the synthesis of isoxazolidines
has been developed. A range 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.
