Hidden benefits: The enantioselective organocatalytic protonation of silyl enolates has been achieved by using readily available cinchona alkaloid catalysts (1) and a latent source of HF that delivers "at will" the active catalytic hydrogen fluoride salt

We report a highly enantioselective, general catalytic system for the facile synthesis of tertiary stereocenters by protonation adjacent to cyclic ketones. The method relies on catalytic decarboxylative protonation of readily accessible racemic quaternary β-ketoesters. A range of substituted cycloalkanone compounds can be accessed through this process with high levels of enantioselectivity. Copyright
