  摘要：

  Several new 1-hydroxy-2-(1,2,3-triazol-1-yl) ethylphosphonates and 2-hydroxy-3-(1,2,3-triazol-1-yl) propylphosphonates as well as the respective phosphonic acids were synthesized from diethyl 1,2-epoxyethylphosphonate and 2,3-epoxypropylphosphonate in the reaction sequence including the regioselective ring opening of the epoxide with azides followed by 1,3-dipolar cycloaddition of omega-azidophosphonates and selected alkynes and finally hydrolyses of the phosphonate esters.
