Abstract: | A proof of concept for the asymmetric organocatalytic aza‐Michael addition reaction of nitrogen nucleophiles with simple and readily available alkyl enoates as acceptor molecules in the presence of a chiral phase‐transfer catalyst has been demonstrated. The desired enantiomerically enriched β‐amino acid derivatives were obtained in up to 86% yield and with enantioselectivities of up to 37% ee. © 2012 Wiley Periodicals, Inc.
