Abstract
An efficient catalytic and enantioselective method for Mannich reactions between trimethylsilyl enol ethers derived from acetone and acetophenone and aryl, alkenyl, alkynyl, and alkyl imines allows the synthesis of a various β-amino ketones in the presence of 1-5 mol % AgOAc and an inexpensive amino acid-derived phosphine.
