Interaction of the O-Benzoyl--aminopropioamidoximes with Lawesson's Reagent and Spectral Characterization of the Products

Abstract

Interaction of O-benzoyl-β-aminopropioamidoximes [β-amino group: pyperidin-1-yl; morpholin-1-yl; thiomorpholin-1-yl; 4-phenylpiperazin-1-yl; benzimidazol-1-yl] with Lawesson's reagent was done in tetrahydrofuran at heating to 70°C during 10 h. New O-thiobenzoyl-β-aminopropioamidoximes were obtained with the outputs 57–96%; they were characterized with the help of physicochemical, IR, and NMR spectra.
