Application

  • 5-Methyl-3-heptanone can be converted into the corresponding gem-dihydroperoxide using aqueous hydrogen peroxide and chlorosulfonic acid as a catalyst at room temperature.
  • It can be reduced to its corresponding alcohol using sodium borohydride in urea/choline chloride eutectic salt.
  • It can undergo condensation with tert-butyl-sulfinamide to form the corresponding chiral tert-butyl-sulfinyl-ketimine, which can further react with ylides derived from trimethylsulfonium iodide and S-allyl tetrahydrothiophenium bromide to form highly substituted chiral aziridines.
