Significance

Using a mixture of lanthanum-based bimetallic catalysts, a variety of ketone nitro­aldol products underwent a stereoablative resolution to a single enantiomer plus the parent ketone and nitromethane. The yields were generally fair, while enantioselectivities were generally excellent, allowing access to a variety of chiral nitro-containing products. The synthetic utility of the products was demonstrated by the conversion of the nitro group into interesting and/or useful functional groups.
