Oxidation of aryloxy-β-aminopropanols () with “activated” dimethylsulfoxide (DMSO) was found to provide a convenient “one-pot” method to synthesize aryloxy-β-aminoketooximes (), without isolation of the unstable ketones . Assignment of Z and E stereoisomers of oximes was based on 1H-and 13C-NMR studies. Spontaneous isomerization of was also observed and discussed.
