N-Propargyl-α-aminophosphonates in 1,3-Dipolar Cycloaddition with Azide-Containing Pharmacophores

Abstract

Some transformations of N-propargyl-α-aminophosphonates synthesized by the Kubachnik–Fields reaction were studied in copper-catalyzed 1,3-dipolar cycloaddition with azide-containing pharmacophores (phenothiazine, tetrahydrocarbazole, carbazole, and 3,5-dimethyl-1-aminoadamantane) leading to the formation of the corresponding 1,4-substituted 1,2,3-triazoles and allowing the introduction of a diethoxyphosphoryl fragment into the molecules of potential neuroprotectors.
