We report a stereoselective and site-specific allylic alkylation of Schiff base activated amino acids and small peptides via a Pd/Cu dual catalysis. A range of noncoded α,α-dialkyl α-amino acids were easily synthesized in high yields and with excellent enantioselectivities (up to >99% ee). Furthermore, a direct and highly stereoselective synthesis of small peptides with enantiopure α-alkyl or α,α-dialkyl α-amino acids residues incorporated at specific sites was accomplished using this dual catalyst system.

The term "Maillard reaction" is used to describe a complex set of reactions in foods leading to flavour generation and non-enzymatic browning.The first step in this process is the so-called Amadori rearrangement: a reducing saccharide and a peptide fragment react to form an Amadori Rearrangement Product (ARP).To be able to do model studies on flavour generation, gram amounts of pure ARP are required.In the present study, glucose-derived ARPs were synthesised from specifically protected and activated starting compounds.After deprotection and purification, pure ARPs were obtained.This is the first time that ARPs of dipeptides have been isolated.
