Abstract

The synthesis of several new pyrrolidine based asymmetric organocatalysts derived from tartaric, glyceric acids and a pyrrolidine moiety is described with a study of their application in the development of an enantioselective aldol protocol. The influence of different proton donor groups, such as a primary hydroxyl or a carboxylic acid group, or their absence, on the efficiency of the organocatalyst was studied. The configuration of the tartrate derived catalysts and the presence of the rigid butane-2,3-diacetal were found to have a strong influence on the stereoselective outcome of the aldol reaction
