Converging on the goal: New chemistry enables the key Cys-peptide-(αthioester) intermediate to be extended by ligation at either the N or C termini in a controlled fashion. This approach forms the basis for a set of novel tactics for the fully convergent synthesis of proteins by the chemical ligation of multiple peptide segments.
