Abstract: Iron(III) nitrate-assisted cycloaddition of (phenylsulfonyl)ethene to arylacetylenes in the presence of KI affords 5-phenylsulfonyl-3-aroylisoxazolines whose treatment with K₂CO₃ provides 4,5-unsubstituted 3-aroylisoxazoles. Both synthetic steps can be performed in a one-pot manner.

Keywords: iron nitrate, nitration, alkynes, 1,3-dipolar cycloaddition, isoxazolines, isoxazoles.
