Abstract
A new synthetic method has been developed to prepare peptides bearing a C-terminal N-alkylamide from peptide thioacids via a radical-initiated dethiocarboxylation process. This method enables the introduction of various alkyl groups to C-terminal amides simply by replacing the amino acid building block. Its application to the preparation of anti-cancer drug ABT-510 is also reported.
