LUMO-lowering organocatalysis has been extended to promote the conjugate addition of S-alkyl and 1-pyrrolyl silylketene acetals to alpha,beta-unsaturated aldehydes, yielding both, syn and anti Mukaiyama-Michael products with high levels of enantioselectivity. This strategy allows for the generation of chemically useful 1,5-dicarbonyl systems and again highlights the utility of organocatalysis. (C) 2009 Published by Elsevier Ltd.
