摘要:
The bis-triazolide of trifluoromethylphosphinic acid is prepared from trifluoromethylphosphorous dibromide, CF3PBr2, and reacted in situ with alcohols. The resulting triazolomonoesters are efficiently hydrolysed and oxidised to give trifluoromethylphosphonate monoesters, as shown for the nucleotide analogues adenosine 5'-O-trifluoromethylphosphonate and 2'-O-deoxythymidine 3'-O-trifluoromethylphosphonate, novel nucleotside esters having a trifluoromethylphosphoryl function.
