Effective dynamic kinetic resolution in the nucleophilic substitution reactions of alpha-bromo amides derived from L-leucine and L-proline is described. The methodology is used with dibenzylamine as a nucleophile in the presence of TBAI and Et3N to provide di- and tripeptide analogues up to 95% yield and >99:1 dr. (C) 2003 Elsevier Ltd.
