for the synthesis of water-soluble ketoxime phosphate prodrugs avoiding the unwanted Beckmann rearrangement is developed. In the first step, a novel in situ prepared phosphorochloridic acid bis-(2-trimethylsilyl-ethyl) (TMSE) ester 1 reacts with the hydroxyimine 2. In the second step, the formed TMSE-phosphate triester 3 undergoes a tetrabutylammonium fluoride mediated microwave-assisted conversion into
