An efficient method for the synthesis of 5-vinyl-2-isoxazolines by Pd-catalyzed intramolecular O-allylation of ketoximes has been developed. The reaction involves Pd(0)-catalyzed π-allyl formation via leaving group ionization or Pd(II)-catalyzed allylic C–H activation followed by intramolecular nucleophilic oxime oxygen attack. This methodology has been elaborated to various value-added products by
