Abstract

Asymmetric cyanosilylation serves as an important tool to convert easily available ketones into cyanohydrins of diverse reactivity. Whereas a large library of organocatalysts and transition-metal catalysts have been identified for monoketones, cyanosilylation of more-complex substrates, particularly those giving enantioenriched vicinal stereocenters, is underexplored in comparison. Here, a pair of recently published kinetic resolution and desymmetrization methods are highlighted for their success in constructing complex vicinal stereocenters by cyanosilylation using tailored aluminum and magnesium catalysts, respectively.
