New Peptide Synthesis†
†
Dedicated to Professor Rolf Sammet on the occasion of his 60th birthday
Graphical Abstract
Alkylphosphonic anhydrides such as (1) are recommended as condensation reagents for peptide synthesis. One advantage of (1) over dicyclohexylcarbodiimide (DCC) is that no sparingly soluble secondary products are formed. With regard to yield and degree of racemization, the new method is just as good as improved DCC techniques, and in some cases superior.
