Abstract

A series of new piperazine phosphoramide derivatives of 4-hydroxycoumarin were synthesized through a facile phosphorylating reaction starting from 4-hydroxycoumarin and various phosphorylating agents. The title compounds were characterized by IR, NMR, electrospray ionization-mass spectrometry, and high-resolution mass spectrometry, and their spectroscopic data were further analyzed to feature the related spectroscopic characteristics of the compounds of this class.
