| | TETRAETHYL METHYLENEDIPHOSPHONATE Usage And Synthesis |
| Chemical Properties | clear yellow to yellow-brown liquid | | Uses | 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 | | Uses | Tetraethyl methylidenebisphosphonate, can be used in the synthesis of tetrazoloquinoline-based mono- and bisphosphonate esters as potent anti-inflammatory agents. It is also an intermediate for the synthesis of new bisphosphonate and bisphosphonic acid derivatives with anticancer and antischistosomal activity. | | Synthesis Reference(s) | Synthetic Communications, 20, p. 1865, 1990 DOI: 10.1080/00397919008053112
