Insights into the Finer Issues of Native Chemical Ligation: An Approach to Cascade Ligations

Maximizing by minimizing: An efficient and broadly useful two-step ligation protocol was developed. Important mechanistic issues of ligation were probed from competition studies on the formation of diastereomeric ligation products. This study provides a valuable approach to facilitate polypeptide synthesis by minimizing protecting group manipulations and intermediate isolations.
