The first chiral electron-poor guanidine organocatalysts were synthesized. The presence of a tunable electron-withdrawing group on the guanidine moiety allows for the modulation of the catalysts' activity. The application of this new class of organocatalysts to the Michael reaction is demonstrated. (C) 2010 Elsevier Ltd. All rights reserved.
