Methods of synthesis of N-alkyl-N'-alkoxydiazene-N-oxides containing a carbonyl group in the beta-position of alkyl or alkoxy radicals were developed. beta,beta-Dinitro derivatives of N-alkyl-N'-alkoxydiazene-N-oxides were synthesized for the first time via nitration of oximes obtained from the Ketones.
Several racemic 1-arylideneamino-3-aryloxypropan-2-ol-N-oxides have been prepared and separated into enantiomers by a lipase-catalyzed transesterification with vinyl acetate as the acyl donor.
