- A practical and efficient methodology for the chemical synthesis of peptides/proteins using a one-pot/sequential ligation is described. It features the use of photocleavable S-protection on an N-sulfanylethylaniline moiety. Removal of the S-protecting ligated materials under UV irradiation provides a readily usable mixture for subsequent native chemical ligation.
