The synthesis of ephedrine (dialkyl phosphorothioate)s has been effected. The method of their preparation and their properties are described. The IR and PMR spectra of ephedrine (dialkyl phosphorothioate)s and some results of an x-ray structural investigation of the spatial structure of ephedrine (diethyl phosphorothioate) are given.
