Angewandte Chemie, EarlyView.A stereospecific, transition‐metal‐free SN2 alkylation of cyanohydrins with chiral non‐racemic secondary tosylates is reported, providing efficient access to enantioenriched α‐tertiary ketones. The method exhibits broad substrate scope, operational simplicity, and excellent stereospecificity, including stereoconvergent reactions of E/Z mixtures of ...
