Application

Reactant for synthesis of:
  • Dual substrate-site inhibitors of 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase
  • Unnatural alpha-amino acid derivatives containing gem-biphosphonates
  • Biphenyl sulfonylamino Me bisphosphonic acids as inhibitors of matrix metalloproteinases and bone resorption
  • Lycopene via Wittig-Horner reaction
  • Alkylaminoethylbisphosphinic acids to target farnesyl diphosphate synthase
  • Aromatic bisphosphonates for use as inhibitors of geranylgeranyl diphosphate synthase

Precursor for synthesis of dendritic polyglycerol anions used toward L-selectin inhibition
