Lipase-catalyzed separation of the enantiomers of 1-arylideneamino-3-aryloxypropan-2-ol-N-oxides. Preparation of optically active nitrones

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.
