The asymmetric aldol reaction is a powerful method for forming carbon-carbon bonds. Small peptides with a primary amine as the catalytic residue catalyze asymmetric aqueous aldol reactions between unmodified ketones and aldehydes to furnish the corresponding aldol products with high ees. The high momodularity of the small peptides should enable the construction of several novel catalysts by combinatorial techniques for the aqueous asymmetric aldol reaction. The remarkably high difference in stereoselectivity between the peptide bond-formation was an important step towards the evaluation of asymmetric catalysis and homochilarity.

Simple peptides and their analogues having a primary amino group as the catalytic residue mediate the direct asymmetric intermolecular aldol reaction with high stereoselectivity and furnish the corresponding aldol products with up to 99% ee; this intrinsic ability of highly modular peptides may explain the initial molecular evolution of aldolase enzymes.

N-Benzyloxycarbonyl amino acid chlorides and α-benzyloxycarbonyloxy carboxylic acid chlorides are readily available by treating the corresponding carboxylic acids with 1-chloro-N,N,2-trimethyl-1-propen-1-amine.They can be immediately reacted with O-, N- and C-nucleophiles to afford peptides, ketones and esters.
