Abstract

Here we show trapping of chiral enolates with carbenium ions, Michael acceptors, and bromine. Silyl ketene aminals, disilyl acetals, and aza-enolates were obtained via Lewis acid mediated enantioselective conjugate addition of Grignard reagents to unsaturated amides, carboxylic acids and alkenyl heterocycles.
