approach for the synthesis of isoxazoline derivatives is reported. This protocol involves 1,3-dipolar cycloaddition between in situ generated nitrile oxides from the corresponding aldoximes using [hydroxy(tosyloxy)iodo]benzene (HTIB, Koser’s reagent) and maleimides, styrene and acrylonitrile. The described methodology is very attractive as it is operationally simple, has broad scope, and does not require
