  Iodocyclization of Hydroxylamine Derivatives Based on the Control of Oxidative Aromatization Leading to 2,5-Dihydroisoxazoles and Isoxazoles

  摘要：

  An efficient method for the synthesis of 2,5-dihydroisoxazoles and isoxazoles using iodocyclization of N-alkoxycarbonyl O-propargylic hydroxylamines has been developed. 2,5-Dihydro-4-iodoisoxazole underwent the cross-coupling reactions without aromatization to afford polyfunctionalized 2,5-dihydroisoxazoles. This process was applied to the preparation of valdecoxib and its 2,5-dihydro-derivative.
