organocatalytic reactions have been reported with various selectiv-ities and mechanistic investigations. In addition to proline, other chiral organic molecules based on thiourea,thiazolidine,4 cin-chona alkaloids,5 peptides 6 and cabohydrates 7 have been screened
successfully as organocatalysts for asymmetric reactions. In addi-tion, some chiral amines and diamines have also been employed as organocatalysts for aldols and their variations with good enanti-oinduction.
Recently an elegant combination of amino oxazoline and proline has been prepared and tested for inducing chirality
in intermolecular aldol reactions. These types of prolinamide-oxazolines are amongst a series of modifications designed on the basic amino acid unit of proline where a second chiral element has been introduced. Such derivatives with two chiral units have been more selective compared to some of the prolinamides pre-pared with achiral amines.
This series of prolinamide-oxazolines are neutral molecules in nature, as the carboxylic acid of proline is
blocked by the amide group
