A variety of α-nitroketones have been obtained from the corresponding olefins in good yields upon reaction with trimethylsilylnitrate-chromium trioxide reagentsystem.

A Facile Approach to the Synthesis of 3-Acylisoxazole Derivatives with Reusable Solid Acid Catalysts
gel-supported sodium hydrogen sulfate (NaHSO4/SiO2) or Amberlyst 15 as solid acid catalyst, and then the corresponding 3-acylisoxaszoles were obtained by reacting with alkynes via the 1,3-dipolar [3+2] cycloaddition. These heterogeneous catalysts are easily separable from the reaction mixture and reused. This synthetic method provides a facile, efficient, and reusable production of 3-acylisoxazoles.
A practical, general protocol for the synthesis of a broad range of α-ketothioamides via denitration of readily available α-nitroketones with sulfur and amines has been reported.
