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.

The plant-growth modulating effect of microbial volatile organic compounds (VOCs) has been demonstrated repeatedly. This has most often been performed by exposing plants to VOC released by microbes grown on nutrient rich media. Here, we used soil instead to grow
